ATLAS S-ONE Handguard

The Aero Precision AR15 ATLAS S-ONE Combo Set 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.

Available in KeyMod™ and M-LOK® profiles with 12” and 15” options (7” and 9” options coming soon).


  • Front and rear picatinny rail
  • Eliminated center of top rail for weight reduction
  • Indexing grooves in 12:00 position for positive grip control
  • Compatible with low profile gas blocks
  • 1.3” Inside diameter
  • 1.5” Outside diameter
  • Compatible with mil-spec AR15 upper receivers and barrels

AR15 Upper Receiver, Gen 2

The Aero Precision 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 and includes the port door and forward assist pre-installed. Get the billet look without paying the billet price!

Gen 2 Upper Features:

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