The innovative design of these models combines the time-tested ar platform expertise of lwrci with an innovative chamber ring delayed blowback operating system that delivers a unique pistol caliber ar shooting experience.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.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.Caliber: 9mm LugerBarrel Length: 8.50"Capacity: 33+1Grips: LWRC Ultra CombatSights: NoneWeight: 5.10 lbsStock Material: SyntheticOal: 22.50"- 25.75"Stock Finish: BlackBarrel Length Range: 8" to 8.99"Weight Range: 5 lbs to 5.99 lbs
