16" Complete AR15 223/556 Upper

The Breek Arms complete AR15 223/556 16" 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 16” Bear Creek parkerized 5.56 barrel and with a black nitride bolt carrier group to give you 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 simply twist on your optional BRK 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
  • Full length picatinny top rail
  • BCA expects 1" MOA with any barrels 16" or longer

Breek Arms is dedicated to bringing our people new and improved products and solutions at reasonable prices while maintaining a high quality product. This feature rich and affordable AR15 upper is just another way of fulfilling our mission.

    As described, functions 100%. Easy plug and play for my lower. The Warhammer upgrade is worth every penny.
