No, not law enforcement cops. Cops as in the Aero precision continuous optics platform! Its a monolithic upper receiver that is MODULAR! You can swap your rails out for different set ups, optics, missions etc!
COP M4 Mid-Length Upper Receiver Kit – Anodized Black
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.
