The Aero Precision FDE M4E1 Enhanced Upper Receiver is a one-piece design combining the handguard mounting platform with the upper. 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. Forged from 7075-T6 aluminum and precisely machined by Aero Precision, right here in the U.S.A.

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.

The M4E1 Enhanced Upper features M4 feedramps, .250 takedown pin holes, and comes assembled with dust cover and forward assist. The M4E1 Enhanced Upper works with Aero Precision handguards, but also fits most BAR-system handguards. Both barrel nut and wrench are included, however these uppers are not piston-kit compatible. Rifle builders, save time, and keep your products from from accidental dings to ensure a sharp looking finished product.
