Aero Precision M4E1 Threaded Assembled Upper Receiver Texas Black

The M4E1 Threaded Upper Receiver features an 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 our new M4E1 Lower Receiver, giving you a billet looking receiver set at a fraction of the billet price.

Features:

• Enhanced forging that gives the upper receiver a “billet look”
• Picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
• M4 Feedramps
• .250 takedown pin holes
• Laser engraved T-marks
• Engraved image of the State of Texas
• Includes threaded forward assist roll pin
