Note: This complete upper receiver assembly has a barrel length under 16” and is therefore subject to all NFA rules and regulations. Know your local laws before purchasing.

The Breek Arms complete AR15 223/556 14.7" upper comes jam packed with features that usually cost you a fortune in order to trick out the plain upper you may have purchased before. Our AR15 complete upper uses quality components that come from trusted companies. The upper comes equipped with a 14.7” Pencil Profile 5.56 barrel for a lighter weight setup. And with an optional black nitride bolt carrier group you will have flawless function when operating. The upper receiver is from Aero Precision paired with a Breek Arms Handguard of your choice. In the front, you have a couple options for the muzzle device. Keep it open to lessen the recoil, or if you want to tame the sound and flash simply twist on your optional Castle Blast Shield. Last but especially not least, the upper can be equipped with our famous WARHAMMER ambidextrous charging handle for easy one handed manipulation. The upper can be placed on any type of mil spec AR-15 lower.

Items Included:


  • Compatible with Mil-Spec AR-15 lowers
