Dirty Bird Industries 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 the rejects). They are then finished with a uniform Mil-Spec Type III hardcoat anodizing 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 from excessive pitting, machined to spec and finished with 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 included

NOTE: Cerakoted options will not have laser etched t-marks
