Aero Precision AR-15 M4E1 Threaded Stripped Upper Receiver - FDE (Blemish)

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

Features:

• New enhanced forging that gives the upper receiver a "billet look"
• New picatinny profile that blends seamlessly with their Enhanced and ATLAS Series Handguards
• M4 Feedramps
• .250 takedown pin holes
• Includes threaded forward assist roll pin
