The COP C4 (Continuous Optics Platform) is a custom configured integrated upper receiver and hand guard system.
This extremely rigid design allows for symmetrical or asymmetrical rail platforms to accommodate a multitude of optic requirements. The hand guard system allows for a free-floated barrel giving the operator superior performance and accuracy.
This system uses any standard AR-15 barrel, not a proprietary barrel system. Barrel nut and wrench are included with the kit. The receiver design also has a fully enclosed dust cover pin which can be removed with the barrel in place. The forward assist and dust cover are already installed.
NOTE: Barrel assembly, bolt carrier group and charging handle not included.
