Overview

Aero Precision's M4E1 5.56mm Carbine Upper Receiver comes fully assembled, minus only the bolt/carrier group and charging handle - the two components any AR-15 fan with even a little urge to customize wants to replace anyway. Aero's M4E1 receiver combines the unique look of a custom billet receiver with the affordability and "mil-spec" parts compatibility of a forged receiver. The M4E1 5.56mm Carbine Upper Receiver comes with Aero Precision's latest Gen 2 Enhanced M-LOK Handguard installed to form a solid, monolithic accessory mounting platform. The full-length Picatinny top rail runs from the rear of the receiver across the entire length of the handguard, whic Mfg: Aero Precision
