Preface

I’ve been using riflescopes since my first BB gun, I’ve always preferred them as a sight device. In more recent years I started using riflescopes from US Optics, my first one almost a decade ago was a 25x SN3 TPAL. An amazing scope that I literally abused and it never lost zero. I’ve also since had several other US Optics scopes of all kinds, you can read more about my experience with other US Optics scopes here. But today I am bringing you a brand new US Optic riflescope, and I am quite excited about it. Today’s subject is the US Optics TXH 3-18×50 riflescope.

I initially saw the TXH at SHOT Show 2024, as I met with the US Optics team we nerded out over this new scope. Its hard to tell everything about a scope indoors, but I could tell enough about it to know that I needed to get it into my mountain shooting country as soon as possible.

Like most US Optics scopes, the TXH is full of great features. First off I really like the 34mm tube, as it gives maximum internal travel for shooting long-range. The popular 34mm tube is coupled with 10 MRAD turrets, which is much better than 5 or 6 MRAD turrets that are common in this price range. Smaller turret values mean you have more rotations, and its easy to get lost on which rotation of the scope you are on.

Zero-stops are another feature that are meant to combat loosing track of which rotation you’re currently on. The TXH also has a zero-stop feature which makes it even easier to stay aware of your elevation settings.

Parallax and focus are done on the left side turret, with a parallax setting as low as 10 Yards. This is very nice for those that intend on using this scope for things like shooting precision rimfire. Illumination is controlled by a rheostat stacked on-top of the parallax turret. It has six power settings with an off setting in between each one.

Adjusting magnification is easily done with the included throw lever, and the ring turns 180 degrees needing only a single motion to go from three to eighteen power. This 3-18x size scope is excellent for a medium range carbine or a light precision rifle. I would feel more than adequate for engaging anything inside a kilometer with ease. The first focal plane MHR2 reticle changes size with power setting, but always gives you accurate options for measuring targets and holds.

Mounting and zeroing the TXH

Mounting the TXH was done using a ZRO Delta 34mm cantilever scope mount. I like the hand tightening fasteners, making it easy to swap from one gun to another. I torqued down the oversized screws securing the TXH into the mount. This scope was destined to end up on my Desert Tech WLVRN, so I used it for the initial host. With the scope mounted properly, I set the rifle up so I could boresight it using my tool less method.

In just a few minutes, I was shooting with the TXH. After getting the rifle and scope zeroed, it was time to set the TXH turret to zero. This was done by using the plastic tool that came with the scope, it has several flat edges similar in shape to a coin-edge. But since they are plastic, you wont damage the turret caps, or over-tighten them either.

Setting the zero-stop is done by loosening the three set-screws of the black inner ring under the turret. Rotating the ring counterclockwise until it touches the stop. Snugging the three screws back down will cause the turret to stop on that fixed point.

Shooting in the Field

With my rifle and scope combination ready for action, it was time to put it to work. Much of the shooting I planned on doing with this rifle would be part of my varmint hunting adventures. Shooting at small rodents in the high Rocky Mountains would be an excellent way to test the TXH. Picking out furry little marmots hiding in and around rocks and trees requires a sharp eye.

As I expected, the TXH looked fantastic in the clean mountain air. The bright images were just what I expected to see, and one of the better parts of scopes in this power range. Its ability to focus on targets as close as 10-20 yards away was impressive.

As is the case with most every scope I’ve ever used, the image suffers a bit at max power. The TXH looses some of its brightness, but I find that as usual when I back the scope off slightly, I find a sweet spot.

Parallax adjustment seemed to be easy to correct, and with the image focused there was almost no aberration’s around the edges. I think I would have preferred the available EMCR reticle, as there are a couple things I would change with the MHR2 reticle. Mainly even out the spacing of sub-tensions, but I like the open center.

US Optics TXH Turrets

I have always liked US Optics turrets, more-so their domestically produced scopes. The turret design of the TXH definitely has a better design than the TS line of scopes. The turret outer ring snaps up and down to lock the setting. But the inner part of the turret only rotates. this is a much more robust design than having the whole assembly pop up and down to lock. That robust feeling translates into incredibly crisp clicks on the turret. They are so clean that you can feel and count them audibly without even looking. Furthermore, the last click as you hit zero has a different sound to it.

Speaking of the zero-stop, this one feels amazing. No sensation of compressing or tension building as you approach it. It is simply a solid stop, like a hammer hitting a rock it stops perfectly on zero every time. The internal ring of the zero-stop allows for two rotations of the turret when installed. If you remove the zero-stop, you will get full range of motion which gives a full 35-ish MRAD range.

The windage turret has five MRAD either right or left once you set it at zero. I rarely use anywhere near that much while shooting, so its more than enough for me.

Tracking the TXH

All the best scopes have accurate tracking, meaning that they actually move the amount they say they do. I’ve checked quite a few scopes over the years, and most of them have been pretty close to their actual value.

My process involves bolting the scope down to an immovable object, and then measuring the actual movement according to the turret value. Finding fixed points downrange allow you to dial the scope up and down, left and right making boxes until the crosshair returns back to the same starting point.

Dialing several box tests two revolutions from the zero-stop to max elevation and back. Additionally ten MIL’s of windage and back, the TXH rendered the same return to zero every time. And measuring the click value against a ruler proved the movements to track well within a small percent of actual. For example; if you dial 7.8 MRAD of elevation for a shot, and the actual movement is 7.791 MRAD. You probably can’t shoot well enough to notice the difference. Especially at a distance needing 7.8 MRAD of correction.

Pros & Cons

Pros

Today we’ll start with the things I like about this scope, which are many. I don’t normally start with price, but today I will. I have a couple other scopes that are comparable in both size and performance, I recently got into a PA GLx3-18×44 for example. After heavily shooting through that scope for a season, I was very impressed particularly with the price. So when I found out that the US Optics TXH would sell for around a hundred dollars less I was astounded. While I like both of these scopes the little TXH easily walks away with the win at that price point, and not just because of the price point.

The optical performance of the TXH is fantastic. I have recently started to notice my eye’s acting their age, but even still I find the clarity of this scope to be well above its punching weight. Its clarity is partially due to the great focusability and immaculate parallax adjustment.

The design of the TXH turrets are very user friendly, and they are built for strength and apparent heavy use. Extra points for ten MIL turrets and a great zero-stop mechanism, a step up from previous versions that restricted overall turret travel. The throw-lever is a nice touch as well, making this scope very quick and controllable.

Cons

I mentioned earlier that I might prefer the EMCR reticle, I like that option over the MHR2. Not that the MHR2 reticle isn’t useful or anything, it just a preference. I doubt it will inhibit my shooting much in real world scenario.

Another thing I would change if I had the ability is the illumination. Scopes in the sub-thousand price range seem to all suffer from a bit of flooded reticle illumination. What I mean by that is with the whole reticle illuminated there seems to be too much. You can combat it by using a lower brightness setting, but I wish the reticle was only partially illuminated. Either way this is a small complaint, as I rarely use illumination, and if I did need it this would certainly work.

Lastly is something perhaps a little more subjective. As much as I love the turrets on this scope, I feel the control surface textures don’t match up. I wish they had made them more similar to the FDN series, just for looks I think it would have strengthened the whole brand look.

Final Thoughts on the TXH

There is no getting around imported optics these days below a certain price point. The optics market has been flooded with many good rifle scope options that are made overseas. It comes as no surprise that most optics companies are offering additional lines that are more competitively priced. This scope does an excellent job bridging the gap between the US Optics high-end domestically produced models, and less expensive imported riflescopes.

The US Optics TXH 3-18×50 is from what I can tell a great option for those looking for a solid precision rifle scope for under $700. Something crazy to imagine a decade or two ago. And coming from a well-known manufacturer like US Optics makes me confident that it has been well thought out and tested. I have heard it’s likely we will see these scopes on shelves later this year, probably just in time for hunting season.

I will continue to use this scope aggressively and frequently to see how it continues to perform. If my experience with other US Optics scopes is any indicator it will have no problem doing that. Follow me to see how that journey goes, I will continue to update here with more info as time passes.

2025 Update: I’ve spent well over a year shooting this scope now, I’ve lost track of how many different guns I have mounted this scope on, re-zeroing, and running the typical cycle of shooting. This scope has done a great job, hasn’t skipped a beat , lost zero, or mis-tracked.
