Description
This complete upper includes the ATLAS R-ONE Handguard. The R-ONE handguards are designed with size and weight in mind, while still providing plenty of real-estate to accommodate any attachment needs the end user may have. The 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.
Aero Precision has taken the pain out of building a legal 14.5" rifle build. These pinned and welded 14.5" complete uppers feature an Gamma 556SL that is permanently affixed to the muzzle providing an overall legal length of 16". Worried you might want to change your gas block? No worries! The outer diameter of the Gamma 556SL allows you to easily slide your gas block over the muzzle device making it easy to change or service your gas system.
If you've had a 14.5" build planned, but didn't want to deal with the hassle of getting it pinned and welded or being stuck with a specific configuration, then our 14.5 pinned and welded barrels/uppers are for you!
This complete upper does not include BCG or Charging Handle. These products may be selected as add-ons under the FINISH YOUR BUILD tab
The muzzle brake that comes with this complete upper receiver is pinned to this barrel. Per the National Firearms Act, the muzzle brake MUST be pinned and welded to achieve the necessary 16" as defined by the ATF for a rifle build.
