About this upper
Aero Precision M4E1 5.56MM Assembled Upper Receiver No Forward Assist FDE is an upper receiver. Finish: Flat Dark Earth.
Manufacturer details
This upper receiver features the same tried-and-true construction and aesthetics as Aero's 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, they 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 they 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.
Custom enhanced forging that gives the upper receiver a ""billet look"" while maintaining the structural integrity of a forged part.
