Aero Precision M5E1 Enhanced Upper Receiver

The Aero Precision M5E1 Enhanced Upper Receiver is a one-piece design combining the hand guard mounting platform with the upper itself. Through superior engineering, we have condensed the parts needed to mount a free-floated hand guard to a mere 8 screws. Since the hand guard 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 your barrel assembly into the M5E1 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 M5E1 Enhanced Upper features M4 feedramps, .2795 takedown pin holes, laser engraved T-marks, and comes assembled with dust cover and forward assist. The M5E1 Enhanced Upper works with Aero Precision hand guards. Lastly, the M5E1 Upper is not piston-kit compatible.

Aero Precision Enhanced Handguards

Aero Precision M5 Enhanced KeyMod / MLoK Hand guards provide a lightweight free float design for your custom M5 .308 build. The enhanced system allows advanced modularity past the current 1913 picatinny rail system. Machined to mil-spec dimensions and engineered to perfection, this hand guard eliminates bulk while retaining strength and stability. The M5 Enhanced Hand guard features a 1 piece free float design, with built in anti-rotation tabs. Rails are scalloped to prevent snags and the top rail is continuous. The inside 1.8″ diameter is compatible with low profile gas blocks, fits most muzzle devices and 1.5″ suppressors. Lastly, M5 .308 utilizes the DPMS High Profile (.210) Tang.
