A3 Upper Half, with 20" inch barrel, A3 Upper receiver and Modular handguard. This 5.56mm caliber barrel is 20" long, threaded the standard 1/2 x 28 tpi, and has an A2 flash hider with the correct crush washer. The barrel is machined from chrome-moly, high vanadium steel and hardened to a U.S. government Mil-spec of Rc 26-32. The barrel, and all external steel parts, are manganese phosphate finished IAW 220.127.116.11 of Mil-STD-171, the U. S. government's recommended protective finish for steel. This finish not only looks great, it affords complete corrosion protection. The barrel is button rifled with 6 grooves, right hand, 1 / 9 twist. The 1/9 twist is best because it handles the widest variety of ammunition and bullet weights. The barrel is mounted on a FORGED A3 upper receiver with built in Mil-spec M1913 Picatinny accessory rail, with the correct rail numbers engraved, made from certified forgings, hardcoat anodized IAW Mil Spec A8625, Type III, Class II, black per No. 37038, Table IX with nickel acetate seal, as per the Mil-spec. The upper features a forward assist and hinged ejection port cover. This kit features a 12" long modular handguard with 4 M1913 spec Picatinny rails. This handguard is machined from aircraft aluminum and hardcoat anodized IAW Mil Spec A8625, Type III, Class II, black per No. 37038, Table IX with nickel acetate seal, as per the Mil-spec. The handguard is massively slotted for efficient cooling can be timed to any rotational position and then locked. The four position gas block is machined from aircraft aluminum and hard coat anodized for long life and makes it quick and easy to attach sights and accessories. The upper is COMPLETELY ASSEMBLED. Drop in your bolt and carrier and let her rip! Since this is a parts kit and does not include a receiver, no FFL is required for purchase.
