The IC-SPR Compliant model is built on the AR-15 platform and configured with fully ambidextrous controls, including the safety, magazine release (paddle-style), and bolt catch/release. This layout supports efficient operation from either side without aftermarket parts.
Its 16-inch spiral-fluted barrel and short-stroke gas-piston system deliver a clean-running, piston-driven setup. The barrel is threaded at the muzzle and fitted with a removable flash suppressor that is not pinned or welded.
The rifle uses an extended free-float handguard with a numbered continuous Picatinny top rail, providing consistent mounting reference points. Folding backup iron sights are installed and ready for use.
For compliant use, it features a fixed stock and a non-pistol, featureless grip, with a 13.0-inch length of pull. The grey aluminum alloy receiver and frame match the overall finish and carry clear factory markings: "IC-SPR 5.56mm" (upper), "LWRC INTERNATIONAL M6IC" (lower), and "CAMBRIDGE, MD U.S.A."
Chambered in 5.56mm NATO with a 10+1 capacity, this IC-SPR includes one Magpul PMAG GEN M3 10-round magazine. It is manufactured in the United States and designated under LWRC part number ICR5PG16SPR.
