Squaring the Receiver Face

At Bexar Arms, we offer you the option to have the face of your receiver squared. Squaring the face of the receiver is an essential step in accurizing your AR pattern rifle, and ensures your barrel seats firmly and completely with the receiver face and is perfectly inline with the BCG raceway in the upper. This allows for a more consistent bolt engagement which evenly distributes force among all of your bolt lugs instead of only a few. This consistent lockup and complete barrel seating can help increase your AR's maximum accuracy potential as well as extend the life of your bolt. While squaring your receiver face is 100% unnecessary for your rifle to function, if you're looking to squeeze the absolute most performance out of your AR pattern rifle, we highly recommend it!

    Areo xl upper

    Posted by Kevin on Aug 20th 2020

    I'm still in the middle of a Franken gun build but this upper should do well on my 40 s&w build. Shipping was faster than what I'd expect in these covid days. And there was a nice personal touch on my invoice where they thanked me for my purchase. An should I have issues don't be afraid to reach out to them. I'll definitely continue to do business with you guys.
