Wish i could give 5 stars. But i purchased these sights on blemish.
The rear sight can stand up to the recoil of the rifle and will flip down after 2-3 rounds.
However, front sight is solid.
Good fit and finish. Works well.
Incredible price, blemish was minute. Think I might start shopping the blemished items first...
Every thing and even more than I expected. Thanks
I had been trying to figure out what I wanted on my 300BLK for a sighting system. So I thought about putting on open sights for the time being. They were blemish sight so I didn't have a lot invested in them. Shipping was fast and customer service was great. Once I had them in my hands the only blemish I could find was some of the paint was peeling being Aluminum I'm not worried about the paint. As for the sights they are basic didn't want a lot invested in them but they went on the rail fine lined up fine and performed great. As for now the only thing I see could be better is the flip up bearing could be tighter they are really easy to lay down. Since they are my primary sights for now I am leaving them up. If I decide to keep open sights I may order an upgrade from AT3. Either way I am happy and will be looking for more stuff from them.
