LOL...like I said, they're "identical to KWA internals". So yeah, the first thing I would switch out is the piston for a full steel rack and ditch the aluminum piston head for a poly carb one.....and voila,one sweet, hot gun that will last.
As for the nozzle, I haven't come across any air leak issues air.
