These complete uppers have been assembled and test fired. They are ready to ship and are plug and play. These uppers are built with a 13.9” barrel that highlights precision accuracy over other brands. We pin and weld a Dead Air (keymount) muzzle device to make the barrel a legal 16” rifle length and ready for your suppressor. Simply snap this beauty onto your lower of choice and enjoy high performance that you can trust at an affordable price. (OPTIONAL MUZZLE DEVICES CAN BE PIN & WELDED ON REQUEST) Our billet uppers are made from 7075-T6 aluminum. CNC machined featuring a very sleek profile. These uppers are impressively built to sustain heavy abuse. The upper receiver is paired with a 13” 6061-T6 CNC machined billet handguard. The MLOK handguard features superior tensile strength and is designed to endure heavy impact without throwing your iron sights or optic out of alignment. The handguard mates direct to the upper and features anti-rotational tabs. The handguard is installed using our steel low profile barrel nut which requires no timing as it fits under the gas system. The 13.9″ barrel is produced from raw bar stock to finished product. The barrel is properly stress relieved after rifling, and extensions are torqued after nitride. Superior quality control system ensures that all barrels are dimensionally correct and bores fall well within their individual tolerance.
