Created from the ground up around US-manufactured Glock magazines, the IC-9 is chambered in 9mm featuring the same ambidextrous controls and performance attributes found in LWRCI s luxury gas-piston AR lineup. LWRCI s commitment to craftsmanship and design excellence is clearly evident in the new IC-9 models, the firearm delivers the high performance that discerning shooters demand alongside the quality and innovation that our customers have come to expect from LWRCI . Constructed of advanced aluminum and steel alloys, protected with hard-coat anodizing, ferritic nitrocarburization, and nickel-boron surface treatments, the IC-9 s MonoForge Upper Receiver with integrated rail-base is lighter and stronger than standard pattern uppers. Coined Forging are struck, heat-treated, and struck again for precise dimensional accuracy and superior surface finish.
