The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Aero Precision reduced the parts needed to mount a free-floated handguard to 8 screws. Since the handguard mounting surface and upper are of the same forging, the system is stronger, and additional lightening cuts save weight and allow more efficient cooling.
Installation: 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.
