LWRC ICMKII 556 12″ SBA3 BLK | ICMKIIP5B12SBA3

The LWRC ICMKII is a compact AR-style pistol that applies LWRC’s short-stroke piston design to a modern, M-LOK equipped platform. This pistol ships configured with an SBA3 pistol brace and a spiral-fluted barrel to reduce weight while maintaining a compact profile. For a dedicated optic that matches the pistol’s fast-handling intent, consider a Trijicon MRO red-dot for rugged, daylight-capable sighting. The ICMKII is well suited to range training and 3-Gun competition where compact handling and reliable operation are priorities.
