LWRC ICMKII SBR 5.56mm 12in TB | 30rd Mag | Black

The LWRC ICMKII SBR is a compact, purpose-built short-barrel rifle chambered in 5.56mm with a 12in barrel, engineered for durable, low-maintenance operation. It uses LWRC’s monoforge one-piece upper receiver with an integrated rail-base and a patented short-stroke gas piston system to reduce fouling and improve consistency. The rifle ships with a Magpul 30-round PMAG and fully ambidextrous lower receiver controls for intuitive operation. As indicated in the product listing, this is an NFA-regulated firearm and requires the appropriate NFA transfer process.

An optic such as the Vortex Strike Eagle 1-6×24 provides a capable, under-$1000 solution that pairs well with this platform for both close and mid-range work.
