You got a sweet deal on that. In fact a steal. I just sold a 80 round drum for it....more then you gave for the gun. Those 30 round stick mags, bitch to load, are about $75 each. I've had two of these and wanted a fullauto .22, but.........
Where do you find more drums? I have a couple people looking for them.
I have seen drums on Gun Broker, Guns America, or similiar sites,you just have to look and get lucky. I know someone that has one and is going to part with it for me.
