Rise Armament 6mm ARC Complete Upper: 18″ Stainless with BCG and Ambi Charging Handle

Features

  • 18″ 416R stainless steel barrel for accuracy
  • 6mm ARC chambering for long-range performance
  • 1:7 twist rate stabilizes heavy projectiles
  • Rifle-length gas system for smooth cycling
  • 5/8×24 threaded muzzle
  • 15.25″ free-float M-LOK handguard
  • Black nitride bolt carrier group included
  • Rise Armament ambidextrous charging handle included
  • Forged billet aluminum upper receiver
  • Black anodized finish
  • Complete and ready to install

The Rise Armament 6mm ARC complete upper solves the long-range AR-15 problem by chambering the ballistically superior 6mm ARC in an 18″ stainless barrel with everything included. This upper works well for precision shooters wanting .308-level performance from an AR-15 lower, hunters needing flat trajectory and energy past 500 yards, and anyone building a dedicated long-range gun without sourcing individual components. The 416R stainless barrel with 1:7 twist stabilizes heavy match bullets while the rifle-length gas keeps recoil soft – bringing complete long-range capability to your AR-15 build with BCG and ambi charging handle ready to go.
