Dirty Bird AR-10 Billet Stripped Upper Receiver

The Dirty Bird AR-10 Billet Upper Receiver is the perfect choice for your next AR-10 build. Precision-machined from 7075-T6 Billet aluminum on state-of-the-art CNC machines, you can be rest-assured the Dirty Bird AR-10 upper will fit perfectly with most DPMS profile AR-10 lowers, including our very own Dirty Bird Ambidextrous AR-10 Billet Lower. Every AR-10 upper is hand deburred and tumbled to remove any sharp edges and provide exceptional fitment.

The forward assist housing and the dust cover have been removed to provide a sleek design and to prevent any potential snag points. All Dirty Bird Billet AR-10 uppers are Type III Class 2 Hard Coat Anodized or are Cerakoted, in house, by our Factory-Certified Cerakote applicants to provide unparalleled durability.

You have Dirty Bird’s word that these uppers will be free from excessive pitting, machined to spec and finished with quality (not purple or chalky) hard coat anodizing.
