Gorilla Firearms 8.6 Blackout GF-10 Complete Uppers are manufactured to strict tolerances using only the highest quality components. Each upper contains:

  • Gorilla Firearms Custom Billet Upper Receiver (DPMS High) and Rail
  • SLR Adjustable Gas Block
  • 8.6BLK 1:3 Twist Barrel
  • Gorilla Firearms Bolt Carrier Group
  • Milspec Charging Handle

Options include:

16″ Barrel with 11.5″ rail

12″ Barrel with 10.25″ rail

8″ Barrel with 7.1″ rail


  • Unlike the AR15 and Mil-Spec, there is no industry set standard for compatibility. This means that not all AR308 parts are guaranteed to work together between different manufacturers.


  • The M5 shares compatibility with several DPMS Gen 1 parts and components. However due to different variances within that category we do not guarantee that all DPMS Gen 1 style components are compatible.


  • Our goal to bring you the tightest tolerances and optimum performance; assembly may require assembly pens to be tapped into place.
