45 degree offset iron sight

Exactly what I was looking for. Put this on my new AR build as a quick fire option next to my red dot. Little heavier than I expected, but I have not made it to the range to try it out yet.

Doug M
45° Offset Iron Sights

Even with a red dot with magnifier (also from AT3), I was able to mount the rear sight properly in a good position. They are exactly what I wanted and expected. Just another reason to trust and rely on AT3's products.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

45 Degree What!!!!!!!!!!!!!!!

Brothers! I scoped my AR15 308 POF piston hybrid, It runs like a stripped A__ Ape. Makes 600 ft easy on 8" gong. Up close things get fuzzy. I miss my Magpul mbus sights. Co-witness no way. Price, workmanship and functionality makes AT3 45's the only game in town.

Good quality—but for marred finish.

Damaged—had paint scratch on top of sight where it would show the most. Didn’t open plastic wrapper and notice till over a week after arriving.

Surprised me

After installation and using my laser bore sight only had to tweak the front one click and the rear was bang on. I did the initial laser sight-in at 25 yards (My back yard) Went to the range did first 3 shot group at 50 yards bottom of the center black. Made one more tweak on the front and didn't touch the rear. Next 3 shot group was 100 yards and put 2 darned near center the first round was left center, I think I may have pulled that as the gun had a new CMC trigger installed. Great product for the money. Excuse the mess in the garage.
