It can ge a good gun when you get the upgrades for it otherwise its crap.The barrel sucks need at least a 14" because the stock is only 10" long. I play only with my friends so thats why I have this gun. It's great if you just mess around.
good gun for beginners and for the money but, you get what you pay for.
