AR15 / M16 complete kit with 8.5" inch barrel and A3 Upper receiver. Item # AR-UHPA3. This 5.56mm caliber Wilson barrel is 8.5" long, threaded the standard 1/2 x 28 tpi, and has an A2 flash hider with the correct crush washer and a correctly sized gas port for reliable function. It sports a carbine length, aluminum alloy handguard. This hand guard is knurled for a positive grip, hardcoat anodized for long life and scratch resistance, and completely free floats the barrel, enhancing accuracy and dissipating heat. It is a two piece design for ease of cleaning. The gas block 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 and fits under the handguard. 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 22.214.171.124 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 .750 under the front sight base and dimensioned to alleviate barrel whip and enhance accuracy. 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 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. The upper is fully assembled, headspaced, and ready for action. The buffer tube is a special design that uses a standard carbine buffer and spring and is protected by a foam cover. This design makes this pistol the most reliable and easily maintained pistol kits available. 4-40 set screw is included to retain the rear takedown pin detent. This parts kit can be used for an AR15/M16 pistol or for a super short entry weapon. All semi auto lower receiver parts are INCLUDED as well as semi auto bolt, carrier, and charging handle. The upper is completely assembled and test fired. Everything you need EXCEPT the stripped lower receiver!
