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!

Bexar Delivers
Ordered a squared aero upper for my new build. Upper looks fantastic. I cannot wait to get the rest of my parts in and put this thing together. Phillip does amazing work and is an asset to the firearm community. This wasn’t my first purchase and definitely will not be my last with Bexar.

Excellent upper
Slick and beautiful assembled upper. Fits my Aero lower like a glove. Glad I went ahead and had the the head squared; it was probably fine though.

Great product from an awsome company
Ordered my upper with face squaring and expected it to take much longer because of this service. 2 days after ordering i received my shipment notice and tracking number. With machining needing to be done i expected it to take much longer but was pleasantly surprised it arrived at my door withing a week of ordering. No tool marks, no scratches, just a perfect out of the box receiver with a shiny squared facing for seating a barrel. Keep up the excellent work, will be referring and doing business with you as much as possible in the future!

Great product and the receiver squaring is amazing!
I love my Aero uppers, but the receiver squaring really rounded it out.
