Aero Precision’s M4E1 5.56mm 16" 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 16" 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 15" handguard, which has plenty of M-LOK accessory attachment slots and QD sling swivel sockets at the 3/6/9 o’clock positions. Texture milled into the flats give you a better grip and add to your gun’s unique appearance.
