The Aero Precision M16A4 Clone Lower Receiver (part no. APAR148017C) is a stripped, black-finished .223 Remington/5.56 NATO lower built specifically for M16A4 clone projects. Aero Precision engraves it with Property of U.S.A. MOD M16A4 CAL. 5.56MM markings, a serial number designation, and cosmetic Safe/Semi/Burst selector markings that replicate the authentic military-style appearance without changing how the receiver functions. This receiver is semi-automatic only, like every other civilian AR-15 lower; the retro engraving is strictly cosmetic. These lowers do not carry engraving on the right side of the magwell. It ships stripped, ready for the lower parts kit, buffer, and stock of your choice.
