State of the art M5E1 platform starts here, with the Aero Precision M5E1 Enhanced Upper Receiver. The M5E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper 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. 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 M5E1 upper, tighten it using a standard AR15 armorers wrench. Slide your rail on and tighten the rail screws. Within minutes you have a modular, free-floated rail.

The M5E1 Enhanced Upper features M4 feedramps, .2795 takedown pin holes (DPMS Size), laser engraved T-marks, and comes assembled with dust cover and forward assist. The M5E1 Enhanced Upper works with Aero Precision M5 Enhanced Handguards. It will not work with other AR10/308 handguards.
