I personally rebuilt it and can’t say it’s a dream come true. After looking for parts I manage to finish it. It has a custom “hop up” changed the gears along with the motor. Comes with two mags one is a flash mag for quick combat reloads. Brand new cylinder and overall everything. I never used it must maybe one short 2 hour battle that’s it. I think I spent more than what I’m asking for.
