A3 Upper half with 20" inch Heavy barrel and A3 Upper receiver.This 5.56mm cal 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 has a four position gas block instead of the standard front sight base which can interfere with optics. It sports rifle length handguards with full heat shields, and a correctly sized gas port for reliable function in full or semi auto. 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 184.108.40.206 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. These barrels are of heavy-weight (.950 diameter under the handguards, .750 under the front sight base) dimension their full length which alleviates barrel whip and enhances accuracy in semi auto fire and helps dissipate the heat of full auto fire. 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, made from certified 7075T6.511 alloy 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 upper receiver is complete less bolt/carrier assembly and charging handle. The upper is fully assembled. Drop in your bolt/carrier and charging handle, check headspace and let her rip! Add $50 for CHROME LINED barrel and chamber.
