This 5.56mm caliber barrel is 24 inches long, and features an 11 degree target crown for muzzle protection. It sports a full 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. This gas block has 4 M1913 Picatinny rails for fast and easy attachment of accessories. The barrel is machined from 416 R, re-sulpherized, gun quality stainless steel, and hardened to a Rockwell C of 28 to 32 for extremely long life, heat dissipation, and complete corrosion resistance. The 24 inch barrel gives a higher velocity, smaller standard deviation in velocity between shots, and greater accuracy than shorter barrels. All external non-stainless steel parts are manganese phosphate finished for long lasting good looks and corrosion protection. The barrel is a BULL contour ( .950 diameter under the handguard and .935 diameter under the front sight base) for optimum accuracy The barrel is button rifled with 6 grooves, right hand, 1 / 9 twist.  The upper is COMPLETELY ASSEMBLED. 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.
