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 their 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 their new M4E1 Lower Receiver, giving you a billet looking receiver set at a fraction of the billet price.

A New Leader in the AR Crowd
Aero Precision receivers are increasingly the most desirable receivers when starting a build. Laser engraved t-markings, 7075 aluminum, and the fit and finish is fantastic. They are forged receivers but have nice angles usually only seen on milled receivers. It's nice to be able to have more distinct angles without sacrificing the strength of forged receivers compared to milled receivers.
