Clean cerakote on mil-spec parts by Scoreg, Verified Owner, November 16, 2022
Received this and a few other parts from optics planet that were made by AT3. Cerakote looks good and matches from part to part. They’re just mil-spec but still looks sharper than my powder coated parts.

noticeablely bends away from lower by dug, Verified Owner, April 12, 2025
Received 2 of them. Both noticeably bend away from the receiver at the bottom. Don’t sit flush and look bad. First bad endplate in 10+ builds. Don’t recommend.

Would not reccomend by BC, Verified Owner, July 31, 2025
I received the endplate and upon mounting it noticed it did not sit flush with my lower receiver, with a noticeable gap on the bottom when the nut was even hand tightened. Took it off and purchased one from Aero Precision instead, would not recommend...

Product Info for AT3 Tactical Mil Spec End Plate for AR-15

This standard endplate is compatible with any mil-spec AR15 lower receiver. Perfect for completing a build that might be missing this component, or simply having a spare part available for your favorite rifle. This endplate is made of steel and can be properly staked into a castle nut to completely secure your buffer tube on the lower receiver. You can also add a little more color to your black rifle with with your choice of Cerakote finish.image

Note: Staking an endplate with Cerakote finish will cause the finish to chip in that position. This is unavoidable, and we cannot warranty the finish for this application.
