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.

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

Features:

  • Front and rear picatinny rail
  • Eliminated center of top rail for weight reduction
  • Indexing grooves in 12:00 position for positive grip control
  • Quick disconnect sling socket at the 3, 6 and 9 o’clock positions
  • Compatible with low profile gas blocks
  • 1.3” Inside diameter
  • 1.5” Outside diameter
  • Compatible with mil-spec AR15 upper receivers and barrels


M4E1 Threaded Assembled Upper Receiver

The M4E1 Threaded Assembled 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. Get the billet look without paying the billet price!

M4E1 Threaded Upper Features:

  • 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
  • Laser engraved T-marks
  • Includes port door and forward assist installed

Light weight, looks great, but not for adjustable gas blocks. Review by F3 Dunphy
Quality
Price
Value
Purchased the combo set for a light weight upper build to match with an Odin Works 16" light weight barrel. Odin Works provided a tunable gas block. Unfortunately, since the loss of the top rail clearance the hand guard barely could fit the the Odin Works gas block unless you did some gun smithing and shaved off a portion of the corners of the gas block. A mil spec gas block fits but caution if you plan to use an adjustable gas block with an unconventional shape because it may not fit or will be touching the hand guard. Reason I gave it 4 stars for Quality. (Posted on 9/25/2017)
