Our state of the art M5E1 platform starts here with the M5E1 Upper Receiver. The M5E1 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.
Ease of installation - Simply insert your barrel assembly into the M5E1 upper tighten it using the included barrel nut and slide your rail on and tighten the rail screws. Within minutes you have a modular free-floated rail.
