LWRCI ICMKIIP5CK12SBA3 | 5.56 NATO | 12.70 in

The LWRCI IC-MKII pistol (manufacturer part number ICMKIIP5CK12SBA3) is a 12.70 inch carbine-class AR pistol built around LWRC’s proprietary short-stroke gas piston system. It features an M-LOK handguard, an internal two-position paddle-style adjustable gas block for suppressed or unsuppressed operation, flip-up front and rear sights, and an SBA3 pistol brace in an FDE finish. For optics, the Vortex Strike Eagle 1-6×24 provides a versatile, durable sighting solution under $1000 and pairs well for close-to-mid range use on this platform.

Applications include range training and carbine-style competition where low-maintenance reliability and modularity are priorities.
