M4E1 Enhanced Upper Receiver Stripped - FDE Cerakote

Our state of the art M4E1 platform starts here, with the stripped M4E1 Upper Receiver. This M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superior engineering, we have condensed the parts needed to mount a free-floated handguard to a mere 8 screws. Since the handguard mounting surface and upper are of the same forging, not only is it a stronger system, but we are able to make additional lightening cuts to save weight and allow for more efficient cooling.
