Upper Receiver Groups

Faxon Firearms complete AR-15 upper receiver groups are a great option to complete your next build. Each upper receiver group is assembled with care from parts made in-house in our Greater Cincinnati facility. Our upper receiver groups include an Enhanced Forged 7075-T6 Type III hard coat anodized upper receiver, one of our button rifled 4150 or 416-r stainless steel barrels, and bolt carrier groups.


The Faxon Firearms ARAK-21 upper receiver group is a drop-in replacement upper for your AR-15 which marries the best of the AR-15 and the AK-47 converting your upper receiver to a long-stroke gas piston operated system. The ARAK-21 is a completely self-contained system that does not require the use of a buffer tube.
