The all-new LWRC IC-MKII Patriot Brown 5.56x45mm Rifle is LWRC International's flagship AR-15 gas piston rifle, designed to surpass the performance of the renowned LWRC IC-A5. The IC-MKII boasts several impressive upgrades, including a longer M-LOK handguard, stronger mono-forged upper and lower receivers and a new butterfly-style adjustable gas key. The M-LOK handguard is designed for easy removal, requiring only the loosening of two screws at the base to slide it off. Like the IC-A5, the IC-MKII uses a 2-way adjustable gas piston system, but with the added convenience of the butterfly-style adjustment key, which can be accessed through the machined holes in the handguard. These enhancements make the IC-MKII a more robust and versatile choice for shooters seeking superior performance and durability.
