416R Stainless Steel Barrel

This 5.56mm caliber barrel is 16" long, with a target crowned muzzle, and a correctly sized gas port for reliable function. The barrel is machined from 416R, re-sulpherized stainless steel and hardened to a U.S. government Mil-spec of Rc 26-32.  All external steel parts are manganese phosphate finished IAW 5.3.1.2 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 Bull barrel contour (.950 diameter under the handguards, .935 under the front sight base, .925 forward of the gas block) dimension their full length which alleviates barrel whip and enhances accuracy in semi auto fire and helps dissipate heat. 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 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 aan Aluminum free float handguard that is knurled for positive grip and a 4 position gas block.  The upper is fully assembled. Drop in your bolt/carrier and charging handle, check headspace and let her rip!
