Here’s a very easy giveaway to get in on. If you want a chance to win one of probably the nicest Bump Fire Stocks available for the AR-15 or AK-47 then all you need to do is head on over to Facebook and “LIKE” both FosTech Outdoors and Student of the Gun. That’s it!! FosTech Outdoors will then randomly pick a winner on September 21st to receive their choice of either one of their DefendAR-15 or Bumpski AK-47 Stocks. If you haven’t already you can check them out at FosTechOutdoors.com. I’ve also included a video of the DefendAR-15 in action below. Good luck!
