The LWRCI ICDI Discovery 5.56 NATO 16? Direct Impingement M-LOK Rifle is a high-quality AR-pattern semi-automatic rifle built on LWRC International’s Direct Impingement system with a “keyless” bolt carrier design for reliable function and simplified maintenance. Chambered in 5.56 NATO, it features a cold-hammer-forged, spiral-fluted 16.1-inch barrel with a 1:7? twist rate and 1/2?-28 TPI threaded muzzle paired with an A2 flash hider, giving it balanced handling and accessory compatibility. The rifle rides on a free-float M-LOK handguard and includes a compact adjustable stock, Magpul MOE+ grip, and fully ambidextrous controls for intuitive operation. With a 30-round magazine included and an optic-ready upper rail, it’s versatile for range use, general shooting, and duty applications while retaining the fit and finish expected from LWRCI.
