C.O.P. C4 Carbine Length Upper Receiver Kit - Anodized Black

The C.O.P. C4 (Continuous Optics Platform) features a custom configured integrated upper receiver and handguard 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.

The carbine length C.O.P. (C4) features a handguard that is properly sized to meet up with an A2 Front Sight Block when used with a carbine length gas system. It will cover the gas block when used with pistol length gas system and low profile gas block.

This system uses any standard AR-15 barrel, not a proprietary barrel system. The receiver design also has a fully enclosed dust cover pin which can be removed with the barrel in place.
