LWRCI IC-MK II Pistol 5.56 NATO 10.5" M-LOK Piston Upper SBA3

The LWRCI IC-MK II is a complete AR-15 pistol upper receiver chambered in 5.56 NATO/.223 Remington, built around a 10.5" barrel with proprietary short-stroke gas piston operating system. This updated Individual Carbine design features a two-position adjustable gas block with paddle-style controls located inside the M-LOK handguard for selecting suppressed or unsuppressed operation. The M-LOK free-float handguard provides modularity for accessories while the piston-driven system delivers enhanced reliability in extreme conditions with easier maintenance than traditional direct impingement systems. Includes flip-up front and rear sights and SBA3 stabilizing brace.
