C.O.P. M4 Mid-Length Upper Receiver Kit - FDE Cerakote

The C.O.P. M4 (Continuous Optics Platform) features 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.

The mid-length C.O.P. (M4) features a handguard that is properly sized to meet up with an A2 Front Sight Block when used with a mid-length gas system. It will cover the gas block when used with pistol or carbine 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.
