With Aero Precision's Enhanced Series Upper Receivers and Handguards Enhanced Really Means Enhanced!

The Enhanced Series begins with an all new state-of-the-art forged upper receiver. The M5E1 (.308) upper receiver is a one-piece design combining the rail's mounting surface with the upper itself. By machining the rail's mounting surface into the upper itself Aero Precision has condensed the parts needed to mount a free-floated rail to a mere 8 screws. Since it is of the same forging as the upper not only is it a stronger system, but it's also lighter and cools more efficiently. 

Near Seamless Rail & Upper Alignment!

Aero Precision's E1 design removes the human element margin of error when it comes to not only installation, but also correct alignment and removing any gap between the upper and the rail. 

Suppressor Ready!

The Enhanced Series Rails have a 1.8" inside diameter that will accommodate most muzzle devices and 1.5" suppressors. A perfect set up for your short barreled suppressed package.
