Product Description

The TSR 100  is a adjustable sight similar to the ones used on M16/AR15 rifles.  Turns your Ruger 10/22 into a low cost training rifle. Currently used by many nationwide in the Appleseed rifleman training program.  FEATURES: 8" Longer Sighting Radius Rear Sight Base mounts solidly to the rear of the receiver utilizing the existing tapped scope base holes. TSR100 comes standard with dual apertures (.062) and is compatible with M16/AR15 apertures. Uses incremental windage adjustment with rugged detent locking. Front sight tower comes with standard incremental detent adjustable AR15 type post designed for the AR15. This gives the shooter a wide variety of aftermarket post designs for the AR15 that work with this Front Sight Tower. (Scale lines in photo were colored in for illustration purposes)  Made with steel parts. Will not work on a 10/22 Tactical as it has non-removable scope mount rail. All Standard 10/22s work. Bull barrels are .920" and requires adapter TS157 not included)

These are EXCELLENT standard military style iron-sights which easily add on to your rifle (a Ruger 10/22 in my case). If you are using these for a Liberty Training Rifle or Appleseed, get the TSR100 model. The difference between the TSR100 and TSR200 is the TSR100 adjusts for elevation only at the front sights, while the TSR200 adjusts for elevation at both front and rear sight as well as for windage at the rear sights (more than what is needed for Appleseed). Do get the front sight tool for adjustment (TS155), on a .22lr you can't use the bullet tip to push down the front sight adjustment pin as you can on center fire rifles. IF you get the TSR200, also get the rear sight elevation adjustment tool (TS211) because it isn't easily adjusted the way it is on an AR15 or similar sighting system. Regarding installation, the Ruger 10/22 has a thin solder on the front sight, so you will have to bang it to break the solder connection and get the front sight to move. Drive the front sight out from left to right (the only way it will move). Once you do, the stock front sight will come out. Use Blue Locktite. The 3rd screw on the front of the front sight (i.e., pointing from barrel to stock) is a pain to get lined up because of the angle it is on. It's better to install it first then slide the front sight into the dovetail, just don't tighten this screw down before doing so. I had to remove a set of Tech-SIGHT'S from a rifle and the Locktite was so strong I stripped the hex bolt screw head trying to get them out. I eventually had to cut the head of the left front sight side bolt to push them out. 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.Read more ›

I will begin with the end. My liking of the TSR100 sight is unqualified. While I have a few nits with the sight, overall I am completely satisfied with it.

I have been shooting Ruger 10/22 rifles for decades. These are superb semi-automatic .22 rifles. I have never cared for the stock Ruger sights for a variety of reasons. Finally, this year I resolved to explore alternative iron sights. I selected the Tech Sight TSR100 because it is essentially identical to the sights that my M16a1 rifle had during my Army service. So at least I was familiar with how it worked! Nonetheless, I was initially skeptical of whether I would be satisfied with the accuracy that I would achieve with this sight.

The rear portion of the sight is easy for the user to install. Not so much the front sight. This involves tapping the original OEM sight out, and I decided that I would have a gunsmith do this part of the installation for me. It worked out just fine.

Taking my Ruger 10/22 now equipped with a TSR100 sight to the range was exciting: would the sight initially be close to zero, or would it be one of those situations where at first the rounds were nowhere near the target at 25 yards? (my sighting distance). After firing a ten round magazine at a 7 inch bull's-eye target at 25 yards from a sandbag rest I was pleased to see that all ten rounds were on the target, slightly high and to the right. This sight adjusts windage from the rear sight and elevation by adjusting the front sight post. After a few clicks to move the POI (Point of Impact) left and down, on the third magazine of ten rounds my rounds were centered on the bull's-eye with a shot group of about 1 inch. I was using bulk Federal ammunition; good stuff but nothing fancy.

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. Those extra inches really help!

All the standard AR peeps and posts fit, so I'm going to install some trijicon parts for low light here in the Alaska woods. For a fast, short-range field gun setup, I don't think you can beat this sight.

I have tried several different after market sights for the 10/22 and the TRS-100 is the best so far. The price is reasonable for the budget minded, and the installation was simple for anyone with basis mechanical skills wishing to upgrade their 10/22 rifle. The sights are solid once installed. Then a laser bore sight and a little time at the range gets these sights zeroed in.
The only con would be if you desire to mount a scope on the receiver, with the predrilled holes that most 10/22's have, you cannot once these sights are installed. You can however still use a forward scout type mount if a scope is still desired.
Overall, good product for the price, ease of installation, and effective on target shooting.

If you're contemplating doing an Appleseed course, this is *well* worth the money. The flip-up rear sight that comes stock on a 10/22 is pretty garbage if you're trying to qualify (hard to adjust, hard to see).

The only problem I had was it's really easy to strip the front sight mounting screw when you're installing it...so go slow and DON'T CROSS THREAD!
