Aero Precision M4E1 Upper

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 and precision machined to work with all mil-spec AR15 parts.

The M4E1 Threaded Upper Receiver is designed to pair perfectly with Aero Precision 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
• Laser engraved T-marks
• Includes threaded forward assist roll pin
• DOES NOT include port door or forward assist

Includes:

• M4E1 Threaded Upper Receiver in Anodized Black
