I've recently seen these things pop up, selling for $199 retail. And for an extra $179 you can get a stock that holds extra magazines. I'm just wondering how sturdy and reliable these things are. They look very customizable and easy to shoot which is great because I can teach my fiance to shoot with them and have fun with them. But their website list a spring to by for the magazines for feeding and kits for extra parts and it just feels like they are expecting it to break after 50 rounds. If any of you own it or have tested them please tell me your opinions and if you would spend money on them. Thank you.
