Aero Precision M4E1 Enhanced No FA Complete Upper 10.5" 5.56 Carbine 9" M-LOK Anodized Black

Aero Precision M4E1 Enhanced No FA Complete Upper, 10.5" 5.56 Carbine, 9" Enhanced M-LOK - Anodized Black This complete upper receiver features the same tried-and-true construction and aesthetics as our M4E1 Enhanced Upper Receivers, without provisions for a forward assist. The M4E1 Enhanced Upper Receiver is a one-piece design that combines the handguard mounting platform with the upper receiver. Through superior engineering, we have reduced the number of parts needed to mount a free-floated handguard to just 8 screws. Since the handguard mounting surface and the upper are of the same forging, not only is it a stronger system, but we can also make additional lightening cuts to save weight and improve cooling efficiency.
