AR15 Upper Receiver, Gen 2 ("M4E1 Threaded")

The AR15 Gen 2 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 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. Get the billet look without paying the billet price!


  • New enhanced forging that gives the upper receiver a "billet look"
  • New picatinny profile that blends seamlessly with our Enhanced Series Handguards


  • M4 Feedramps
  • .250 takedown pin holes
  • Lazer engraved T-marks


ATLAS S-ONE Handguard

The ATLAS S-ONE is the newest addition to the Aero Precision Handguard lineup. Machined from 6061-T6 Aluminum, the S-ONE line of handguards are designed with size and weight in mind, providing the perfect handguard for your lightweight build. Our proprietary ATLAS attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.
