Practical fit!

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.

Hi Jurell, sorry to hear about the issue with the rear sight. If you can send us an email with your order information to support@at3tactical.com, we'll be glad to set you up with a replacement.
Can't tell bless are used

Good fit and finish. Works well.

Incredible price, blemish was minute. Think I might start shopping the blemished items first...

We are glad to hear that you are pleased with this blemished product and look forward to helping you with any future orders.
Great back up sights

Every thing and even more than I expected. Thanks

Back up sights

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.
