LWRC International I ICMKIIP5PBC12SBA3 PST 12.7" Carbine

The LWRC International IC-MKII P5PBC12SBA3 PST 12.7" Carbine is a purpose-built short-stroke piston rifle engineered for operators who demand reliability in high-stress tactical environments. Designed for law enforcement, military, and professional civilian shooters, this carbine delivers the accuracy and durability required for close-quarters combat, breaching operations, and precision rifle work at intermediate distances. The 12.7-inch barrel strikes an optimal balance between velocity, handling, and concealment without sacrificing performance.

Built on the proven IC-MKII platform, this rifle features LWRC's proprietary short-stroke piston system, which cycles cleaner and cooler than traditional direct impingement designs—reducing carbon fouling and extending component life in sustained-fire scenarios. The P5 rail system provides modular mounting for optics, lights, and accessories across the full length of the handguard, enabling rapid reconfiguration for mission-specific loadouts. With the SBA3 stabilizing brace, the carbine delivers enhanced control and shoulder support, while the precision short barrel generates minimal muzzle flash signature, critical for low-light operations and team coordination.

This configuration is ideal for entry teams, vehicle operators, and shooters requiring rapid target engagement in confined spaces without compromising accuracy at 100+ meters. The IC-MKII P5PBC12SBA3 excels in duty roles where ergonomics and modularity are non-negotiable, and the short piston stroke generates significantly less wear on bolt carriers compared to direct impingement systems. Installation of suppressors, red dots, and tactical lights is straightforward via the P5 mounting system, making this carbine a versatile foundation for evolving threat responses. Whether configured for duty or defensive use, this LWRC platform delivers the performance pedigree trusted by professional operators.
