I'm considering picking up a couple of slide fire stocks, one for an AK, the other for an AR in case I need to increase my volume of fire during a SHTF situation. I'd like to hear people's opinions of them, especially from TGT members who own or have fired them. I've watched several videos and they seem to quite controllable, at least in the AR and look like they'd make a great MDU (MOB DISPERSAL UNIT), especially with a Beta mag. Your thoughts, Gentlemen?
