What is the AERO PRECISION - M4E1 5.56 Assembled Upper Rcvr Threaded w/AR15 Semi-Cut Blk?

The M4E1 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 Aero's 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.


FEATURES

  • The M4E1 Threaded Upper Receiver is designed to pair perfectly with Aero's new M4E1 Lower Receiver giving you a billet looking receiver set at a fraction of the billet price.
  • The enhanced forging that gives the upper receiver a ""billet look""
  • New picatinny profile that blends seamlessly with Aero Precision’s Enhanced and ATLAS Series Handguards
  • M4 Feedramps
  • .250 takedown pin holes
  • Includes threaded forward assist roll pin
  • Includes port door and forward assist
  • M4E1 Threaded Upper Receiver in Magpul‚ FDE Cerakote
  • Port Door and Forward Assist installed

Available with a standard "M16 Cut" commonly found on M4 upper receivers or an "AR-15 Semi Cut".
