Our state of the art M4E1 platform starts here, with the M4E1 Upper Receiver. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superiorengineering, 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.

Ease of installation – Simply insert your barrel assembly into the M4E1 upper, tighten it using the provided barrel nut and wrench, slide your rail on and tighten the rail Screws Within minutes you have a modular, free-floated rail.
