Dirty Bird AR-15 Stripped Upper Receiver - OD Green

Dirty Bird AR-15 Stripped Upper ReceiverBuilders 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.Features 7075-T6 Aluminum Forgings (forge marks may vary) M4 Feedramps .250 takedown pin holes Laser-etched T-marks Port Door (Dust Cover) and Forward Assist not includedMade in the USABacked by Dirty Bird Industries' Limited Lifetime Warranty
