The GF Custom Division of Gunfire just released a custom Nerf Gun... just kidding. They released a Lumberjack Zombie Killer custom SAW AEG that uses the MugenFire Custom Chainsaw Zombie Killer Kit for the M249 Series. This is not only an external custom work as seen in the paint job but they also did some surgery in the internals, upgrading it to perform better than the stock gun.
