Aero Precision M4E1 Enhanced Upper Receiver Assembled AR-15 No Forward Assist Aluminum Black

Aero Precision M4E1 5.56 Enhanced Upper Receiver No Forward Assist Anodized Black. 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. Ease of installation - Simply insert ybarrel assembly into the M4E1 upper tighten it using the provided barrel nut and wrench slide yrail on and tighten the rail screws. Within minutes you have a modular free-floated rail.
