LWRC ICMKII SBR | 5.56mm | 14-inch Barrel

The LWRC ICMKII SBR is a compact short-barreled rifle chambered in 5.56mm with a 14-inch cold-hammer-forged, Black Nitride-treated barrel. It uses LWRC’s patented short-stroke gas piston system and a monoforge one-piece upper receiver with an integrated rail-base for alignment and durability. Controls are fully ambidextrous and the rifle ships with a Magpul 30‑round PMAG. Consider pairing this platform with a Vortex Strike Eagle 1-6×24 for a versatile optic under $1000 that covers close-to-mid-range work.

This configuration is well suited to precision-oriented range training and tactical competition use where a compact, low-maintenance platform is desired. It is an NFA-regulated item and intended for lawful ownership and use in compliance with applicable federal and state requirements.
