Live Free Armory LF9CH85012 Challenger 9mm Luger 17+1 16 Black Nitride Threaded Barrel, Flat Dark Earth Cerakote Pic Rail Aluminum Receiver, 15 M-LOK Handguard, Battle Link Minimalist Black Poly Stock, Black Poly Grip, Rifle

The Live Free Armory Challenger 9mm PCC operates on a straight blowback system and does not require a gas block and gas tube as traditionally found in other AR15s. The direct blowback system uses the kinetic energy generated from the discharge of the cartridge, to push the bolt back and cycle the action. The Challenger is compatible with standard frame Glock G17/G19 pattern magazines. The receivers are machined from 6061-T6 billet aluminum; free float handguard measures in at 15" M-LOK compatible and free float handguard. Includes magazine & hard case.
