Pistol shooting, like most shooting disciplines has benefited greatly from technological advancements. Incredible improvements have made todays handguns lighter, faster, more accurate, and reliable. One of these many improvement is in the sight market, pistols have long relied on the simple task of lining up a front and rear sight as you press the trigger. But today we will discuss the hot and competitive red dot sight options that are frequently replacing traditional iron sights. We’ll also look at it from the perspective of home defense use.Read the whole story on Guns.com
Low Power Variable Optics (LVPO’s) have been flooding through the firearm market for years now, likely due to the proliferation of medium-range carbines. It didn’t take long for shooters to realize the value of variable low power optics, but what makes an LVPO shine over another?
Sig Sauer has long been a big name in the firearms industry, I’ve been a big fan as long as I’ve been a gun owner. So it came as no surprise several years ago when Sig brought their own line of optics to market. What was a surprise, at least to me, was how invested I would get.
My first Sig optics was a Tango 6 5-30, a high powered riflescope with all of Sig Sauer’s bells and whistles. It has been a great scope for several years, and still enjoys its place on one of my favorite rifles.

Every hunting or shooting trip has a list of essentials, and at the very top of that gear list you’ll find things such as guns and bullets. But for many of us, it’s not very far down that list that you’ll find binoculars and rangefinder. Today we are discussing the Sig Sauer Kilo 3000 binoculars, which bring the laser rangefinder and binoculars onto the same line.

Many years ago, when I first stumbled down this rifled rabbit hole, I would daydream about the high-end and prestigious rifles I saw in magazines and movies. The internet had not yet become the superhighway it was destined to be, but as it developed I could also visit websites and court those beautiful works of art. Not only was it the rifles, but the impressive optical sights that accompanied them. My dreams of owning such a piece of artisanship seemed unattainable at the time, but I never could have foreseen just how far down this hole I would go.
Years would pass, more than a decade, and I found myself the proud owner of what I had always considered a dream scope. US Optics had always been one of the brands I was smitten with, maybe it was the incredibly robust design that seemed overbuilt for what many would consider standard use. On top of their strength, US Optics scopes had a mechanical attractive flair. It was like looking at top-fuel race engine, you could see all the little things that made it work its magic, and that enticed me even further.
That first US Optics scope was an ER-25, it was the first but far from the last. I’ve since had four more, with the latest being the newest offering from US Optics, the Foundation Series 25X. The Foundation series is USO’s latest line of top tier telescopic sights, made here in the US. The FDN25X boasts some impressive features, some you would expect, and others you might miss if you didn’t pay close attention. The 25X uses a fairly standard 34mm tube and 52mm objective, manufactured from 6061 T6 aluminum, it shares a nearly identical body with its predecessor the B25. But there is more, the FDN25X has the new EREK3 elevation turret with 11 MRAD per revolution, a 180-degree throw magnification ring, the new JVCR reticle (my favorite) with illumination available in red, blue, or green, smooth parallax adjustment, and an internal bubble level.
As I opened the box of the 25X and first picked it up, I was surprised at the weight. At thirty-four and a half ounces, it’s not exactly light but it seemed light for its size. I was expecting it to weigh more. I surely wasn’t going to waste much time, I wanted to get this scope mounted and get shooting with it. I mounted it on the rifle it was ordered for, my custom built 257 Blackjack. It is a lightweight carbon fiber hunting rifle to haul all over these Rocky Mountains for Mule Deer, Elk, and likely a few Antelope as well. The 25X makes a great companion optic for the Blackjack, it stays supersonic beyond two thousand yards, and its energy, drop, and wind deflection makes it ideal for long-range shooting. The 25X has been designed and built for just such shooting, with high-quality lenses to give a clear picture of distant targets. The JVCR reticle gives fine wind holds and holdovers, with .1, .2, and .5 subtensions.
So with the 25X mounted in rings on a 20 MOA scopebase, I wandered off into the hills to get it zeroed and to put it to the test. Zeroing the scope was simple, the new EREK3 elevation turret was easy to figure out with a brief revision of the manual. I removed the center screw on top of the turret and adjusted my reticle with the provided hex wrench. After a couple adjustments, it was zeroed perfectly and my elevation set to zero. Normally I slowly work my way out from closer targets to more distant ones, but that day, I went straight for the long shots. The first shots after zero were 1230 yards, I dialed 6.5 MRAD on the EREK3, and fired a few shots. After getting the wind call right, they were hammering the steel. The EREK3 turret is a good combination of stiff, and crisp. Not too hard to turn, but firm enough to avoid accidental movement.
The clicks are both audible and tactile, adjustments are easily made from the shooting position by simply counting the clicks either felt or heard. The magnification ring is also a welcome improvement, with only 180 degrees of rotation, you can go from 5x all the way up to 25x with one movement. Instead of having to release and turn again like other scopes. It’ also easier to turn than previous models.
After zeroing my scope, I swapped out the scope base for a 30MOA, to get the scope closer to an internal mechanical zero (to avoid the extremities of erector movement). And with it freshly zeroed, the turret had a full twenty-one MRAD of elevation available. It is highly unlikely I will ever use that much elevation, according to my ballistic computer, twenty-one MRAD will take the supersonic Blackjack to 2159 yards.
The JVCR reticle is one of my favorite reticles, I’ve got another one in another US Optics scope. The .2 MRAD marks are all over the reticle, giving a quick and easy reference for adjustments. The open center floating dot makes a perfect reference point when trying to shoot tiny groups on paper, and the open space around it will make it easy to hold center on any of the animals I plan on hunting this fall. I ordered green illumination on the scope, mainly because I’ve had red on every other scope I’ve ever had and wanted to see something different. I’m not overly worried about it, as illumination has rarely been used in most hunting scenarios I’ve been in. But for that occasional need, it is sure nice to have.
One little thing that I found that did bug me perhaps, is an abnormal crescent shaped shadow when the scope is dialed to either of its extremities. This is normal as US Optics has it listed under their FAQ’s on their website. To be fair, it is only visible at low power (less than 8x), and only when the EREK3 turret is almost all the way up or down. I think it is very unlikely that it will ever be an issue, because if Im dialed all the way up, I’ll very likely be zoomed in at least to 12x or more. And if it is an issue bottoming out the scope, then you’ll need to use an additionally canted base. Like I said, a small issue, but one you may want to know about.
Another very cool feature of the Foundation 25X is the internal level or anti-cant device as it’s often called. I always loved the idea of having it inside the scope, but so many times its been done poorly. Not that I have anything against it being external, especially good ones you can see from the shooting position. But it is so much nicer to see in real-time, through your aiming eye without taking it off the target. The way US Optics executed this level is very nice, I ordered the internal level, but it is so subtle that I didn’t even notice it the first time I looked through it. It is tucked neatly at the bottom of the field of view, and like I said, its so low profile that you actually have to make an effort to see it. I’m not sure if the engineers at USO want you to look at the actual bubble itself, or if you are meant to see the highlight reflecting on the bubble as your reference point, either way, it is very handy when you’re in the shooting position.
I also tested the scope for actual click value, which can vary greatly in rifle scopes. I tested the click value by measuring the turret movements against the values of the reticle, as well as against a ruler at a set distance. By doing this you can tell if the clicks actually represent the value claimed. I’ve never tested one that came out perfect, but this one is close enough for my purposes. Under 10 MRAD of adjustment, the actual value was no more than .02 MRAD off of claimed. And at 20 MRAD, it was just over a tenth MRAD from claimed value. I am not a rocket surgeon, but I think its safe to assume that the difference between claimed and actual is spread progressively across the curve as elevation increases.
In addition to testing click value, while I had the scope clamped down solid I also checked the tracking and for reticle cant. Cranking the turrets up down and left and right shew no inconsistency, they always returned back to the exact same spot as I counted the clicks. No noticeable movement in the reticle either, as I zoomed from one magnification to another.
The only thing I haven’t been able to test so far with the Foundation 25X, is its durability over time. My First US Optics scope took such a beating I was sure it would break, banging into rocks, falling off the tailgate onto concrete attached to a twenty-pound rifle, stuff like that. But I was blown away when not only did it survive these events, but didn’t even lose zero. That is a pretty hefty standard to live up to, and I hope that the Foundation scopes are up to it. Time will tell, I certainly don’t plan on dropping it, or bashing it against rocks, but who knows what the future holds?
There is no way this rifle and scope aren’t coming with me for hunting season this year. The 257 Blackjack will light up anything I intend to hunt, and coupled with the impressive view from the Foundation 25X, it should be unstoppable. I am extremely anxious to get up into the high country, and get comfortable and effective with this rifle and scope. You will no doubt be hearing from and seeing more pictures of us in the fall.
Low Power Variable Optics (LVPO’s) have been flooding through the firearm market for years now, likely due to the proliferation of medium-range carbines. It didn’t take long for shooters to realize the value of variable low power optics, but what makes an LVPO shine over another?
I’ve had several different models from a wide range of manufacturers, and today we will discuss in depth the US Optics TS8X.
The Tactical Sport 8 power LVPO is one of several great scopes I’ve been able to shoot in the offshore line of scopes from USO. So far they have proven to be a great option for shooters in my opinion. I have been shooting USO scopes for many years now, and to be completely honest I was a bit worried when I saw they were releasing a more affordable line of scopes. My concerns were quality and performance, for which USO’s are well known. My concerns were assuaged with the TS20x, which quickly became one of my favorites. The TS8X has so far been just as good an experience.
Why an LVPO?
I also have the TS6X, which is the little brother to the TS8x. I wanted the 8X because having used several 1-4’s and 1-6’s, I wanted just a little bit more power for seeing those downrange targets. Again in my opinion, a 1-8 or 1-10 is about perfect for a medium range rifle, for distances around six to eight hundred yards. The TS8X fit that spot perfectly in my estimation, and with the RBR Reticle, it would give me plenty of holdover points for shooting at those further distances.
The TS8X features a 30mm tube, with adjustable diopter eyepiece, covered turrets, and an illuminated front focal plane reticle.
Many manufacturers have moved to the 30 or 34mm scope tube now, it gives a larger tube to pass light through, as well as allow a larger erector to increase the internal mechanical movement of the scope. The parallax is fixed for 100 yards, which leaves the diopter eyepiece focus the only adjustment for the image seen. This is common in most LVPO’s, particularly in this price range. If I had one wish for the TS8 it would be adjustable parallax, I frequently shoot well beyond 500 yards with this scope and others like it. The ability to adjust parallax for those distance targets would be very welcome.
Another feature that thankfully is becoming more commonplace, is the reticle placed in the front focal plane (second focal plane models are also available at a lower cost). This means the reticle is magnified with the power setting of the optic, keeping the reticle values always the same regardless of power setting.
The RBR reticle is illuminated red, with an adjustable rheostat for brightness. It also features both MRAD hash marks (both whole and half) as well as range based holdover points, including wind holds at five and ten MPH.
With the stiff competition in the LVPO market, the TS8X fits in the middle ground of price range. There are many options that are far less in price, and many others that cost double, triple, or more.
My initial concerns about quality were more based on mechanical performance and robust construction. I knew that due to its price point, it would likely not have the same optical quality as scopes costing more, which I was okay with.
Speaking of optical quality, I found the image to be bright, and clean. Not much to complain about there, but don’t expect to see the same image as a $1600-$2400 scope.
I found the RBR reticle to be very useful at distances out to nearly 1000 yards, at 8X it could possibly be a little thick for tiny targets, but I don’t expect many people will be doing benchrest or squirrel hunting at that range. For real world shooting, such as echo targets inside 600 yds, it is perfect. The rifle its currently mounted on will be doing some coyote hunting, and I’m very confident that anything inside 800 yards will be easily identified, targeted, and engaged using the RBR.
As I mentioned above, the reticle features both MRAD marks, as well as estimated drop and wind marks. This is handy, because if you need an honest elevation or wind call, you have the actual MRAD values. Whereas if your shooting at the aforementioned coyote, you can use the drop values according to how far away he is.
I mounted the TS8X on my Desert Tech MDR, which at the time was a sixteen-inch 223. The scope was easily zeroed with no tools, and in no time I was shooting steel all over the range.
I love using the scope at 1X, with the reticle lit up, it is just like using a red dot scope. Up close shooting at steel, animals, or whatever else is easily done with both eyes open. Cover the target with red as you break the trigger will give you sure hits.
I then switched out the barrel for the new Hornady 6mm ARC barrel, to see how the TS8X would match up to its ballistic curve.
Without even rezeroing the scope, I was in business, perhaps more a testament to the rifle than the scope. I later made a few corrective adjustments, and the rifle was punching centers very consistently. The click values of the turrets seemed to be close enough to values marked, but to be honest, I hardly had to move them.
Stretching the rifle out would require using the drop points indicated on the RBR reticle, I figured they would be close since the 6 ARC is not too far off of the 223 trajectory it is based on.
It was close enough to be dangerous that is for sure, at 960 yds I shot over the target. The 6 ARC has less drop than a 223 at that distance, so I held a corrected hold (7MRAD) and a bit of left wind for a perfect center punch hit.
I followed it up with a few more shots to confirm, inside I was giggling like a child watching the trace of my bullets on the way to the target.
I’m not sure if its the TS8X or just better optics that we are spoiled with today. When I first started shooting these farther distances, it seemed like 10X was barely enough, and 15-25 was more like what you needed for shooting long range. But I found shooting almost everything inside a kilometer to be relatively easy with the 8X of this little USO.
I recently took a LE Carbine LVPO course and was extremely happy with the way this little scope ran on the range. We engaged targets all over from 50 to 600 yards in every position you can imagine, I was able to use the wind holds to get some great hits on windswept targets boiling in mirage.
I guess the technology is catching up, soon one thousand yards will no longer be a long range benchmark. It will be more like medium range for drills at a beginners carbine class. If you find yourself on that spectrum, the US Optics TS8X will fill the need for a medium range optic. And it will do it without needing a signature loan to checkout, and you’ll still have the quality and guarantee US Optics has always put on their scopes.
Riton Optics is a relatively new manufacturer of optics, since their start in 2013 they have been working in the Arizona heat to make affordable sighting optics without sacrificing quality.
My first encounter with Riton Optics came a year or so ago, when I put their RT-S MOD 5 6-24X50 scope on one of my rifles. I wasn’t sure what to expect as Riton was relatively new to me, but in a short time the scope’s performance had earned my praise. That same scope has been hauled all over these Rocky Mountains on my Tikka , dropped, snowed on, rained on, used as a crutch, and still maintains a perfect zero. Its no stranger to distance work, these past two seasons it has been used to take five mule deer and two cow elk from two hundred to eleven hundred yards. So I can say with pretty good certainty that these scopes are robust enough for western hunters.
I recently talked myself into one of Riton’s newer and bigger scopes, the RT-S Mod 7 4-32X56. The Mod 7 is definitely a step up in both price and performance from my Mod 5, at more than twice the price, the Mod 7 delivers quite a few more features to the optics aficionado. Both scopes are front focal plane (FFP), which means the reticle is magnified with the power adjustment. This feature allows shooters to use the reticle for accurate holdovers and corrections regardless of the magnification setting. The 8X zoom of the Mod 7 gives a substantial power range from 4X up to 32X, like many scopes, however, I found the very top end of the magnification (29-32x) to be too dark and aberrated to be very useful in the field. It was fine for shooting paper targets up close though.
The PSR reticle featured in my Mod 7 was also a significant step up from the Mod 5. I say step up, some might call it stepping out, the PSR reticle is a bit busier than some. It is a “Christmas Tree” style reticle, with a broadening grid of wind and drop values. I am growing more and more fond of these kinds of reticles, and this one is done very well. Subtensions are clearly marked (on the evens) so you can keep track of your holds, and the marks are thin enough to not bother your view of potential targets. A hollow center and .2 Mrad hash marks come in handy when doing long-range work. The illumination rheostat allows shooters to adjust reticle illumination to fit their surroundings.
Speaking of Mrad, the Mod 7 is available in Mrad which made me very happy. It was one of few complaints I had with my Mod 5, that it wasn’t available in anything other than MOA. Seems like most Riton optics are MOA, could be related to their military background, but I am glad to see newer products available with an Mrad option.
The Mod 7 has a 34mm tube, this again is a step up from the Mod 5’s 30mm tube. The bigger tube allows for more internal travel, giving the Mod 7 a total of 30 Mrad of elevation adjustment. That’s more than enough elevation for your average long-range shooter.
Another feature I appreciated on the Mod 7 was the integrated throw lever on the magnification ring. Some call it a “Cat Tail”. You can run the scope with or without it, the throw lever gives you more purchase when trying to adjust the power ring, not a big deal, but a nice touch.
The Mod 7 also features a zero stop in the elevation turret, something the Mod 5 did not. This feature is handy, as you can return your elevation turret to zero without even needing to look at it. This will save you from a miss by being a rotation or more off.
One of the features both scopes have that I don’t like is there isn’t graduation marks on the turret housing to show which rotation you are on, to be fair it is much less of a problem on the Mod 7 because there are only two turns. The Mod 5 has several more, making it hard to be sure which rev you are on unless you keep track in your head.
I mounted the Mod 7 on my Desert Tech SRS A2 rifle, which seemed like a good fit for the scope. With the new hunting weight 6.5 Creedmoor barrel mounted in the rifle, I figured it would make a good companion for this years elk hunts.
But first I took the rifle to the range to get a good solid zero and check a few other things. My first impression with the Mod 7, was that the eye relief seemed to be just a bit touchy. Not so much as to be a problem, just more so than I was used to. I quickly zeroed the rifle and adjusted the zero stop per the instructions, easy enough and very functional. I then took the rifle up into the mountains to do some more testing at further ranges. I was very happy with the optical clarity of the Mod 7, even when looking at animals and trees at a mile or more away, it was a very clean and bright image.
As I mentioned earlier, the quality does degrade some at the very upper end of the scopes magnification, this is something I have noticed with most scopes including the Riton Mod 5. This is a phenomenon I have noticed on almost all riflescopes, but it is significantly less an issue as the price tag goes up.
It doesn’t bother me much as I rarely use a scope at its maximum power setting, for that matter I rarely use them above 60-70 of their maximum. The glass clarity of the Mod 7 is a great improvement over the Mod 5, as it should be at this price point.
The turrets on the Mod 5 have a push pull locking system, whereas the Mod 7 does not. I am torn a bit as to which I prefer, sometimes I like having my turrets locked, to avoid involuntary elevation changes. And other times I like just being able to turn the turret without having to unlock it. For hunting, I think I prefer the locking system, but for range or competition use I would prefer it without.
The turrets are plenty stiff so as not to be inadvertently moved, the clicks are plenty audible, though I would like them a tiny bit more defined. The line between too stiff, and to mushy a click is a hard line to walk sometimes.
As it turns out, I really enjoyed the throw lever on the magnification ring. To be honest I couldn’t describe the tension on the magnification ring, because with the throw lever it doesn’t even register.
It didn’t take long for me to get quite proficient shooting with the Riton Mod 7, so when the time came to put this rifle into action I was quite comfortable. The late season elk hunt had arrived, and I took my Riton topped SRS up into the snow covered mountains. The first shot I was given was some 475 yards away from a young cow, I dialed the 2.0 MIL on the Mod7’s elevation turret, and pressed the trigger. The cold and clean mountain air was visibly disturbed by my shot, I watched the trace cut through the bright image before me as I followed the shot in. I watched the cow drop, kick, and slide down the snowy slope.
The Riton Mod 7 has turned out to be a strong, clear, accurate and repeatable rifle scope. I look forward to using it more in the future.
Im a sucker for scopes, you might say I have a weak spot for them. I have used most of the very best scopes, and Ive also used many that weren’t worth straining my eye to focus through them. Part of my affliction is due to being spoiled for some time now, and I blame US Optics for it, at least partially. I have had several of them over the years, and they have earned their keep in my safe.
US Optics has a history for robust builds, with nail driving strength. They have seen many changes over the years, and we could argue surely over the pros and cons. But for me, only one thing matters, whats on-top of my rifle, and how does it perform.
As a riflescope addict, I was interested when US Optics launched their Tactical Sporting line of scopes, the TS Series. Like any true addict I rested not until I had the TS 20 in my hands. It was love at first sight.
My initial impression of the TS 20 was its weight, it seemed light for a USO. This new TS line was clearly a more economical series of scopes, so I expected a simpler construction. Lightweight, and a very clear and clean image were both very welcome features. The JVCR reticle was new to me, and well received. I prefer the newer “Christmas tree” style milling reticles, and I found the JVCR to be very handy to use. The offset two tenth windage holds made perfect sense when hurriedly making a wind call. And like most good reticles, even numbering to keep track of your holds. With as many as ten mils to hold over, and five wide for windage, it makes a perfect companion for todays ultra-flat shooting rifles.
Another feature that impressed me very quickly was the focus/parallax adjustment, which is adjustable down to ten yards. At first I didn’t think it was a big deal, but when I dialed the scope down to 2.5X, I realized that this scope could almost be used like a red-dot. If I ever had any up close shooting to do such as approaching a wounded animal, I could simply turn on the illumination, and mark the target with the red cross and pull the trigger. This to me seemed like a very handy feature for a scope I would surely use while hunting. And yet with the max power of 20X from the scope, there are few things I would not be able to shoot at inside my distance envelope.
The turrets of the TS20 are ten MIL per revolution, that for me is a minimum. Long gone are the days of five MIL per turn scopes, that was so 2010. The clicks are clean, and you can both feel and hear them as you turn the turret. The TS20 has an interesting zero-stop feature, but it requires you to limit the rotation to one turn only. Not a big deal for many things, but since I like to live on the edge, I decided to pull any stops and run it wide open. One complaint if you’ll allow it, the turret housing isn’t numbered to help you keep track of what revolution you are on. Bit of a pet peeve of mine, but not a deal breaker by any stretch. The tension of the turrets, power ring, and focus knob were all just right, not too hard to turn, but stiff enough to avoid accidental movement while packing it around.
I already mentioned the parallax/focus adjustment, but just next to it on the left side of the scope, is the rheostat to adjust the illumination on the JVCR reticle. It’s your standard 1-10 clicks with an off position in between each setting. 10 is bright enough to use as a red-dot in dim daylight, and 1 is dim enough to use with night-vision and thermals.
With 24 useable MILS of elevation from its 34mm tube, the TS20 is a very useful long range tool. The rifle it currently commands only needs 5MRAD of elevation to get to a thousand yards. But even if you are shooting a 308 you wont have a problem getting way out there. But with it’s super low power setting, and 28 ounce weight, it is a good option for a long-range hunting rifle as well.
In the field the TS20 performed exactly like every other USO I’ve ever fielded. Click values were consistent, and lined up with my known ballistic data. I keep coming back to it so forgive me, but I love the high and low range of this scope. I never thought I would want a 2X precision rifle optic, but I sure am glad I have one now. In the field was the best place to see the value.
I am not huge on high magnification, I rarely use my scopes above 20X. So the TS20 is right in the middle of where I want all my X’s. Even at max power the image is still clear, and the reticle is very useful. Even so, I usually find my power ring somewhere between 10 and 15. It is at those medium settings that I find the optical magnification and reticle proportions to be ideal, both for targeting, and making corrections.
I mounted the TS20 on three different rifles, first on my Desert Tech SRS A2, and then on my MDR. Regardless of which caliber I was shooting I had every confidence that the TS would keep up. Whether it was hunting varmints on the foothills around my home, or chasing big game like mule deer or elk through these big Rocky Mountains. I’ve never had to worry about my US Optics scopes while traipsing through the brush, and no amount of bumps, drops, or bouncing around in the bed of a truck has ever knocked them out of zero. The heavy recoil from my 300 Remington Ultra Mag didn’t phase the scope, and neither did the repetitive cycling of my 450 Bushmaster MDR, it just kept on ticking.
The Tactical Sporting Series of scopes from US Optics looks like it has a bright future. The scopes are well made, and fit a price point that opens the door to a less expensive market than historically available to those wanting US Optics products. The premium Foundation Series remains the flagship of US Optics quality, I may need to get one of those too, but for now I will enjoy the view from this little TS20.
When a company like Sig Sauer jumps into the optics market, paying attention is a must. I was more than happy to get my hands on a couple specimens early on, and I was very happy with my purchase.
The Sig Sauer Tango line of optics is marketed towards precision shooters, long-range shooters, and hunters, as well as tactical marksmen in the LE/MIL community. I’ve been exposed to quite a few good optics in that realm, so I wanted to see how Sig stacked up.
For the purpose of this article, I will be comparing two of the Tango series of riflescopes. One is the Tango 4 which is a 4-16X44, the other is a Tango 6 5-30X56. The comparison will simply be an evaluation as these scopes are peers of different levels and price points.
For starters, let’s look at the features they share, then we will look at them individually.
All Tango series scopes feature Sig’s HDX coated lenses for optimal light transfer, waterproofing, Lock-Down turrets, and one free laser-etched turret that is matched to your custom load data and atmospheric conditions.
Both the T4 and T6 are Front Focal Plane (FFP) optics, which means the reticle is placed after the magnifier inside the scope. This means the reticle will grow and shrink with the magnification setting. I prefer this configuration as it makes reticle usage more uniform, regardless of the power ring setting.
Both scopes are available with the MRAD/Moa milling reticle, or the Mrad/Moa DEV-L reticle, for those that prefer one system over the other.
The T4 and T6 also have the available MOTAC™ (Motion Activated Illumination) that initiates when motion is detected and shuts off when motionless.
The differences between the two scope are probably where most people are going to make a choice. The T4 is a 4X scope, and the T6 is a 6X, the T6 allows a wider choice of magnification from 5X all the way up to 30X. The T6 also has a larger diameter tube, it’s 34MM tube allows the T6 a greater internal adjustment range. To this larger tube is owed the 12 MRAD (30 MOA) per revolution of the turret. The slightly smaller T4 has a 10 MRAD (25 MOA) of adjustment per revolution of the turret. The 4X magnification on the T4 also gives it a shorter magnification range of 4-14, depending on your application these two different ranges of adjustment could make your choice for you.
The T6 that I purchased, also features Sig’s Level-Plex anti-cant system. It is a digital system that uses internal sensors to tell you when the scope is level or not. When engaged (by pushing the outer end of the parallax turret) there are two small illuminated arrows visible through the reticle. You simply adjust the cant of your rifle following the indicators, and when the rifle is level the indicators go dark, showing that the rifle is level. It is a simple and very quick to use system.
On the Range
Shooting the Tango 4 and 6 made me like them even more. The overall clarity of both scopes was very good, and the bright images made target acquisition and spotting hits and misses a piece of cake. Whether in the bright midday sun or in the waning light of evening, I found the scopes presented more than a satisfactory image.
I did find that for shooting groups that I really appreciated the 30 power magnification of the T6, and the DEV-L reticle provided very precise measurements for both corrections and wind holds. The simpler MRAD Milling reticle in the T4 was also very useful for those who might want a reticle that isn’t so busy. And the lower magnification of the T4 made it a great option for my hunting rifle. Lighter, smaller, and easier to quickly bring onto target.
The process of zeroing the scopes, and setting the zero stop was simple, quick, and effective. In no time I had them zeroed, and was dialing them up and down for distant shots. The Level-Plex system on the T6 proved to be very handy in the field, a simple push of a button engages it, and I never had to take my eye off the target. And it turns itself off after a few minutes. I also like the locking turrets on the scopes, raising them unlocks the turret for smooth rotation, and once set, you can push them back down to lock them in place and avoid accidental adjustments.
If I had to say I didn’t like anything about the scopes, it would probably be regarding the sliding up and down of the turret. I have no basis to prove this theory other than feel, but it seems that when the turret is raised it is not as firmly supported. It feels as if you were to knock it against something hard in the up/unlocked position it could be easily broken. Again, I have no evidence to prove that, it is just a simple observation. To be fair it feels rock-solid when it is down in the locked position.
Perhaps the only other gripe I have is likely a simple defect that is easily repaired. The two fiber optic illuminators that indicate the setting on the power ring seemed to be poorly mounted on my T6. One of them came out and was lost, not a big deal, but something worth noting. I usually don’t focus too hard on the actual setting of the magnification ring anyways, I just adjust it till it looks right to my eye, and shoot.
I think that both of these Sig Sauer optics are fantastic scopes, they definitely come in at two different price points so you can pick one the one that best fits your budget. The T4 at its $719.99 MSRP is a great competitor for the sub $1000 FFP Milling reticle scope market, I think it would compete very well against any scope in that group. The larger and much more expensive T6 MSRP $3,119.99 (as tested) is in another group altogether. I would say pending a few more hard trips into the rugged mountains, and it surviving the beating therein, I would put it against any scope in the 2k to 3k dollar range. The quality is there for sure, the only concern I have yet is with durability over time, but so far I have no reason to think it won’t
clear that hurdle as well. It is quite clear that the engineers at Sig Sauer Electro-Optics took great care in every little feature, whether it is the griping surfaces of adjustment knobs, or something as simple as aesthetic angles and accessories. And with an unlimited lifetime warranty, you can confidently put one of these scopes to work today.
