Review: Great sights for Steel Challenge - At 50, my eyes are not what they used to be and black on black irons just was not working for me anymore. As such, I replaced the sights on my mid-90’s era Ruger 22/45 with this sight set for rimfire steel challenge matches. The difference in visibility and sight pickup speed is incredible as they are just so much easier to see. Installing the sights was about as simple as you could hope for when it comes to changing pistol sights. The factory front sight is held in place with a single flat head screw and the rear sight leaf has an elevation screw and a single 1/16” pin. Remove the two screws (one in the front sight and one in the rear sight), tap out the pin and reinstall the new sights in the reverse order. Just remember to add a drop of blue Loctite to the front sight screw before putting it back in. From there, all it takes is a quick trip to the range to get the sights back on target.
Review: Slightly tricky to install, but they work great! - I installed these myself on my Ruger MkII bull nosed 22. Find a high quality screwdriver that's a perfect match for the front sight screw so you don't ruin the screw. You have to push the little pin out in the rear sight. I used a very small allen wrench as a punch to push the pin out using a plastic faced hammer to bump it out. Don't lose the pin, and don't lose the little spring that pushes up on the upper part of the site. There are Youtube videos to show you how to do it right if you can't figure it out. I took it to the range, and right away my alignment left right was perfect and dead on center. I adjusted the rear sight in the vertical direction one or two clicks at a time until I was dead on in the vertical direction. Both my daughter and I were getting nice clusters in a nice little baseball sized spot in the bullseye area from about 15 yards out. Better than I was ever able to do with the stock black sights. The sights are much easier to see in the dim lighting of the indoor firing range. As far as I can tell so far, the quality is great. No problems whatsoever.

### ⭐⭐⭐⭐⭐ quality and affordable product
*by M***R on July 30, 2014*

great sights and they fit the Ruger mark III great and out of the box were close to zero. they also fit my Ruger 22/45 perfectly but the front site is a bit long and has to be removed if you intend to use the factory scope mount. this is a bit of a hassle if you intend to take a scope on and off frequently but shaving a little off of the back end of the site fixed that problem and did not seem to effect the integrity of the site itself. i have used them under late dusk lighting and the optics pick up the light very well providing a clear sight picture in low light, perfect for small game hunting. I was also surprised to find out that they are the exact same manufacture and model that Ruger sales from their official website. My father ordered these sights straight from Ruger and wound up paying nearly $30 more.
