Dirty Bird AR-15 Stripped Upper Receiver OD Green Anodized

Dirty Bird AR-15 Stripped Upper Receiver Builders know that not all mil-spec forged upper receivers are created equal. Sub-par forgings suffer from pitting and structural defects, poor anodizing can result in a purplish or chalky finish that doesn't last, and sloppy matching can result in mis-sized lugs, burrs, or other machine marks. The Dirty Bird Industries AR-15 Stripped Upper Receiver is precision-machined to M16/M4 Mil-Spec using top-quality forgings (NOT rejects). They are then finished with a uniform Mil-Spec Type III hardcoat anodizing or Cerakote, and laser-etched t-marks. These units are quality checked throughout the process to ensure consistent quality from unit to unit. You have Dirty Bird's word that these uppers will be free of excessive pitting, machined to spec, and finished with a high-quality (not purple or chalky) hard-coat anodizing.
