Question: I noticed your company is based out of South Carolina.  Are you tech sights made there?
Document: The Tech Sights company is a family owned and operated business with several well made products. The TRS100 is a standard upgrade for any Liberty Training Rifle. We use the LTR's in our Appleseed clinics where we teach military inspired rifle marksmanship.I can't be any more enthusiastic about these sights. You won't be disappointed.
Great accuracy improvements I noticed on my part after sighting in which didn't take much. I like training with iron sights and these give a much better picture then the stock river 10/22 sights I've been working with.They also feel well made and with a little blue loctite haven't budged
The sight comes with instructions for how to move the POI left, right, up, and down. Unlike my GI sights, this is not written on the sight itself, which would have been nice.Tech Sight makes a TSR200 sight which allows fine elevation adjustments to be made using the rear aperture. I had at first wondered if I should have sprung for this slightly more expensive sight.
If you have a newer 10-22, the dovetail may be marginally larger. Be sure to use loctite. If there's a visible gap, either tap the dovetail tighter with a drift, or see a gunsmith. Tech-Sights is very responsive to customer service and will help if needed.The sight radius and pattern is excellent, an improvement over factory, and much easier to adjust. A well-made product.
This setup beats the open sights that come with the 10/22 by a wide margin. Very fast target acquisition, and strong build - it's actually made of METAL! !I suggest you also get the adjusting tool when you order the sight, it really simplifies your setup. I mounted these on a 10/22 Compact, so the improved sight radius was a real plus.
I've ordered Tech-Sights for a number of guns and as always I'm very satisfied, the solid construction is second to none. The only issue I have, which isn't even a big issue is on my all weather 10 22, the front sight didn't tighten all the way down. Its very close and the aim isn't at all messed up by the issue. It is just one of those things that makes you uncomfortable in terms of such an important part of your rifle.
I purchased these sights and a USGI cotton sling to make an Appleseed ready training rifle. The TSR100 is, in a word, perfection. I had a gunsmith install them for about 20 dollars and sighted them in quickly and precisely at the range (note: you will definitely want the sight adjustment tool Tech Sights also sells. You can use the tip of a rifle round but you will very likely scratch the sights or the finish).
Moral of the story, once on correctly, they won't go anywhere. No, you can't add a scope without drilling and tapping your receiver to add more mounting holes once you put these on. {:-( Sighting in with Tech-SIGHT'S is a dream and easily done; front elevation-rear windage. Remember the acronym FORS= Front Opposite; Rear Same. These sights are a solar system better than the stock sights. You won't be disappointed! I hope this review helps.
I can state from bitter experience that sights designed this way always result in loss of zero sooner or later. That will not happen with the TSR100.The sight picture with the TSR100 is very easy to work with. This is a functional and effective sight which is why the US Army adopted one just like it for the M-16a1 rifle.A few points. Firstly, this sight is not easy to adjust unless you have the Tech Sight TS155 tool that is designed for it.
This is the best modification I have ever made to my Ruger10/22.. Great product! High quality workmanship and worth every penny!
