Aero Precision M4E1 Threaded Assembled Upper Receiver 
Black
 
The M4E1 Threaded Upper Receiver features a new angular machined design that helps it stand apart from standard mil-spec upper receivers. This upper receiver features the same enhanced body profile as our M4E1 Enhanced Upper Receiver but is threaded to accept a standard AR15 barrel nut. It is forged from 7075-T6 Aluminum, precision machined to work with all mil-spec AR15 parts and includes the port door and forward assist pre-installed.
 
The M4E1 Threaded Upper Receiver is designed to pair perfectly with the new M4E1 Lower Receiver, giving you a billet looking receiver set at a fraction of the billet price.
 
Features:
New enhanced forging that gives the upper receiver a "billet look"
New picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
M4 Feedramps
.250 takedown pin holes
Includes port door and forward assist
Includes:
M4E1 Threaded Upper Receiver in Anodized Black
Port Door and Forward Assist installed
