Sig Sauer Tango 6T 1-6

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.
What is the Tango 6T
Todays subject is about a newer generation Tango 6, the the Tango 6T which is a smaller Tango, a 1-6 Low Power Variable Optic. The 6T features Sig’s high quality and clear lenses for which they are well known. The 1-6 power 6T features a 30mm tube and a front focal plane 5.56 horseshoe ballistic reticle with illumination.
There are a couple different configurations for the 6T, the one I ordered came in FDE only. It also features a line lengthwise down the side of the tube, this eases the mounting of the scope by giving a reference point to evenly seat the scope in the rings. There also came a “cattail”, which is a clamp-on handle to give the user better purchase when trying to adjust the magnification setting.

I mounted the 6T in the Strike Industries ASM mount, an adjustable scope mount that can cantilever the optic out to several different positions. The ASM is a sexy looking companion for the Sig 6T.

After mounting the scope, it was time to zero it, an easy task using the finger adjustable turrets. When not in use the turrets are capped. I installed the CR2032 battery into the illumination turret and lit up the Horseshoe reticle. The 8 position rheostat has an off setting between each number, and also has a push-pull lock to avoid accidental adjustment.
On the Range
My first impression on the range was the image, my eyes were swept from their sockets by the crystal clear and bright image. I am more of a 1-8 fan than a 1-6, but this 1-6 is so beautiful I’d have a hard time turning it down for two more X’s. The 6T has parallax set to 150 meters, so shooting targets that are out there a little further is not a problem.
This was very convenient because I ran the 6T on two different rifles, both of which were very capable downrange performers. First it was mounted on the Armalite M-15 Comp Rifle, a match grade competition rifle built specifically for 3-gunning. I found the M-15 to be very accurate, and with the Tango 6T mounted on it, it was a near unstoppable setup. The low power setting of the Sig made up close targets easily and accurately engaged with both eyes open. And zooming in to 6X gave me enough magnification to pick out distant targets, and the Horseshoe reticle had very handy hold points for those distances.
I never expect ballistic reticles to match perfectly, its nearly impossible unless you are shooting the exact same ammunition in the exact same conditions as those who designed the reticle. The same goes for custom scope turrets, but the good news is that its pretty close. Modern flat shooting cartridges have a fairly similar trajectory so the drop points on the reticle are certainly close enough to be useful.

I also mounted the Sig 6T on my Desert Tech MDRX, which is a multi-caliber rifle. I shot it using both 223 and 6mm ARC barrels, both of which have been very accurate and have done well at various ranges. The 6T felt right at home on top of my MDRX, a much more compact rifle than the Armalite. Maneuvering around obstacles for shooting positions was much easier, and regardless of how close or far away the targets were, the Sig provided a beautiful sight picture with bright images. I keep bringing that up, but that may be the part I like the most about this scope, the optical clarity.

There is more to it than just optical clarity though, the engineers at Sig paid attention to so many little details. Little things like the texturing of control surfaces, high visibility green fiber optics markers around the magnification ring, and other little features that make you feel good about purchasing this scope.

The turrets of the 6T are .2 MRAD per click, which matches the MRAD reticle inside. The clicks are very clean and audible, and the grip surfaces inside the turrets are actually rubberized for easier grip whether using gloves or your bare fingers.

As far as the reticle itself, this might be one place where I wish they had put just a tiny bit more into it. Some people like a simple and clean reticle, while others like a reticle with many useful hold point to use. Being that I am a bit of a distance junkie, regardless of the rifle I’m using at the time, I find myself in the second camp. I like a reticle with plenty of hold-over positions to use and accompanying wind holds as well. While the reticle in the 6T is plenty useful, it wouldn’t have hurt my feelings to see a bit more detail to the reticle. That said, Sig also offers the 7.62 Extended Range reticle in this scope, which is better for that kind of shooting. I completely understand that most people might not need or care about this, and if you like just a few simple hold-over points, you will more than likely love this reticle.

Conclusion
In a market that is flush with many great options across nearly every price range, the Sig Sauer Tango 6T stands out as a spectacular LVPO. I think you would have to spend significantly more money to get a noticeably better scope with these same features. This while the 6T is significantly better looking than scopes that are only 10-20% less on the market. So at least in my opinion, it would be worth spending a little bit more to step up the Sig Sauer Tango 6T.

Strike Industries Adjustable Scope Mount (ASM)

I go through a lot of scopes, not like you think though. I find myself constantly switching optics back and forth, from one rifle to another. One of the reasons I can getaway with it is because of quality scope mounts. And today I’d like to share a little bit about the latest one I have been fortunate to use.

That scope mount is from Strike Industries, a company I am well familiar with. They make all kinds of firearms accessories, the ASM is the first scope mount from Strike that I have used. The ASM is a 30mm set of rings, joined together as one billet piece of aluminum. It does come with ring reducers should you choose to mount a 1” tube scope. The base and rings are held together by a few screws, that also allows one of the paramount features of this mount. The rings can be slid fore and aft to use the mount either as a standard scope mount, or as a cantilever mount. The base of the mount features a recoil lug and two claw clamps to attach to the pic-rail of the rifle.

These features make this mount extremely useful, particularly if your like me and switching back and forth between rifles.
The design and style that comes with most Strike Industries products wasn’t lost on this unit, its clean lines and slender features make it both attractive and unlikely to snag on clothing or other gear.

I like that they used appropriate sized fasteners, some scope rings use insufficient screws that are easily stripped or broken. And I like that there are nearly zero exposed clamps, or screws and such to hangup on. This minimalist design style likely reduces the weight of the mount.

This scope mount is a handsome and useful piece of equipment, no matter which of its four positions you need, I think you will be very pleased with it.

US Optics TS8X

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.

Features
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 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 RT-S Mod 7 4-32X56

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.

The Riton Optics RT-S Mod 5 6-24X50 mounted on my Tikka T3 25 Creedmoor

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 in the Riton Mod 7

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.

Turret details and throw lever on the Mod 7

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.

US Optics TS-20X Rifle Scope

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.

The USO TS20 mounted on my Desert Tech SRS A2

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.

US Optics has always helped me put food on the table

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.

The TS20 mounted on my all carbon 257 Blackjack

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.

The USO TS20 played well with everything, especially this clip-on thermal

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.

This young buck couldn’t escape into the dusk, not from this combo. 450BM/MDR/TS20

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.
