Bull Gear CNC M249 & PKM Gearbox (9mm Bearing)

The Bull Gear CNC M249 & PKM Gearbox allows the weapon to operate smoothly and reliably under high internal stress. This gearbox shell is designed to use standard Cylinder, piston, piston head, and spring guide, excluding nozzle. Crafted from CNC steel this is a highly durable upgrade part that will last a long time! With such a strong gearbox you have more options for internal upgrades without worrying about parts being brittle and weak. What is amazing about this is that it will accept standard V2 (M4) gearbox Cylinders, Pistons, Piston heads and Spring guide, only the nozzle remains original. Being able to accept standard V2 parts drastically changes the suffering of unable to find quality parts to keep the gun-running.
