About this upper
Aero Precision Prcsn M4E1 Uppr 10.5" 5.56 is an upper receiver. Finish: Black.
Manufacturer details
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, 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.

A note on accuracy. We work hard to keep every listing correct, but specifications, images and compliance details come from many sources and can contain errors or change without notice. Images may show a configuration that is not California-legal. If a detail on this page matters to your decision, call us and we will confirm it against the actual firearm before you order. The compliance information here is general in nature and is not legal advice; California and local laws change, and the configuration described is confirmed at the time of sale. All sales are subject to applicable federal, state and local law and to the buyer's eligibility to purchase.
