This thing is modeled after a 22LR MP5 so that explains the weird muzzle Shoots 200 fps with .20 at 300 rounds a minute. Very slow rate of fire. Uses the super cheap battery style and the one that comes with it doesn’t fit In The stock so you will have to get creative. Best used as a backyard plinker or just a kids first gun to learn with. It’s long so shipping will be a bit expensive since I can’t fit it into a smaller box for shipping. Thanks for looking.
