The LWRC IC-PSD 5.56mm NATO 8.5" 1:7" 1/2x28 Black Personal Security Detail Short Barreled Rifle (NFA) ICMKIIR5B8 is a compact, short-barreled rifle built on LWRC International’s proprietary short-stroke gas piston system, delivering full-size rifle performance in an ultra-compact package. Chambered in 5.56 NATO (.223 Rem compatible), it rides on a cold-hammer-forged 8.5? barrel with a 1:7? twist optimized for control and consistency in a short configuration, and utilizes a 1/2?-28 TPI threaded muzzle for muzzle devices or suppressors. Finished in black, this model includes a free-float modular rail system, LWRCI Skirmish flip-up iron sights, Magpul MOE+ grip, adjustable compact stock, and fully ambidextrous controls for intuitive handling. With a 30-round magazine included and a rugged build, the IC-PSD SBR is ideal for close-quarters performance, personal defense, or compact tactical roles.
