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!
