Aero Precision AR-15 Enhanced Upper, Quantum Keymod 15"

Aero Precision is famous for making outstanding Parts and Firearms. So much so, that many companies, such as Spikes Tactical trusts Aero Precision to fabricate their lower receivers. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Since the handguard mounting surface and upper are of the same forging, not only is it a stronger, but also a lighter system.
