The DefendAR-15 AR-15 bump fire stock was recently debuted over at Fostech Outdoors. It works pretty much like the other bump fire stocks for the AR-15, but unlike the other stocks, I actually like the way this one looks. The DefendAR-15 is made out of 6061 aircraft grade aluminum and fit both the fixed stock and CAR AR-15s. They currently go for $499 over at Fostechoutdoors.com.
