This Lewis Machine and Tool AR-15 Pistol features the MLC 5.56 Monolithic Upper Receiver combined with the MARS Ambidextrous Lower Receiver. The upper features an 11.5” barrel chambered in 5.56 NATO with a 1:7 twist rate and is held in the receiver by two Torx screws and allows for quick removal of the barrel from the system. The monolithic upper and free float M-LOK handguard are forged from a single block of aluminum and the barrel nut system provides a full 360 degrees of force to ensure the barrel is locked in. The upper receiver is compatible with a variety of LMT barrel lengths and calibers.
