Aero Precision M4E1 Upper Receiver
Aero Precision’s M4E1 Stripped Upper Receiver is forged from 7075 T6 aluminum, like a regular mil-spec receiver, but with angular external contours that add the strength - and custom look - of a "billet" receiver.
It accepts any mil-spec AR-15 bolt/carrier group (not included) and fits on a standard AR-15 lower. Includes ejection port cover and forward assist (not shown).
Features:
7075 T6 aluminum forging, final machined to accept standard AR-15 parts.
Hardcoat anodized finish, matte black.
M4 feed ramps.
.250" takedown pin holes
Laser-engraved T marks on the Picatinny top rail.
