Aero Precision M4E1-T Complete Upper featuring the ATLAS S-ONE Enhanced Handguard. Key features include front and rear picatinny rails, eliminated top center of rail for weight reduction, compatible with low profile gas blocks.

It is forged from 7075-T6 Aluminum, precision machined to work with all mil-spec AR15 parts and includes the port door and forward assist pre-installed.

The M4E1 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.

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.
