Description

Enhanced M4E1 Upper with Internal Barrel Nut, Aero Precision

The Aero M4E1 Enhanced Upper has a unique design and core function that separates it from standard AR-15 uppers. Instead of the typical threading for a barrel nut, the enhanced upper has a built-in assembly to support Aero Precision’s Enhanced Handguards. The internal steel barrel nut supports the barrel exclusively – effectively eliminating deflection when mounting laser modules to the handguard.

This upper receiver features the same enhanced body profile as the threaded M4E1 Upper Receiver, which matches with M4E1 lowers. It is forged from 7075-T6 Aluminum, precision machined to work with mil-spec AR15 parts, and includes the pre-installed port door and forward assist.

Note: This upper receiver will not work with standard handguards. Use Aero Precision Enhanced or Quantum series handguards only.
