Product Description

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.

Features
  • Works with standard AR15 components
  • Perfect for your custom AR15 build
  • M4 Feedramps
  • Includes threaded forward assist roll pin
