Description

UPGRADES THE STANDARD UPPER RECEIVER TO M4E1 THREADED UPPER RECEIVER!!! (SO IT CAN MATCH THE NEW M4E1 LOWERS)

MUST HAVE A COMPLETED UPPER RECEIVER IN CART

(Upper parts kit is installed)

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, precision machined to work with all mil-spec AR15 parts and includes the port door and forward assist pre-installed.

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:

  • 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
  • Lazer engraved T-marks
  • Includes port door and forward assist

Includes:

  • M4E1 Threaded Upper Receiver in Anodized Black
  • Port Door and Forward Assist installed
