Product Info for Aero Precision M4E1 16in 5.56 Enhanced No Forward Assist Complete Upper Receiver with Flash Hider

This complete upper receiver features the same tried-and-true construction and aesthetics as M4E1 Enhanced Upper Receivers, without provisions for a forward assist. The M4E1 Enhanced Upper Receiver is a one-piece design combining the handguard mounting platform with the upper receiver 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. This complete upper receiver does not include BCG or Charging Handle.image
