Depends on if you like the fit / slant in your hold... - FAB Defense Sniper Rubberized Buttpad for GL-Shock and GL-MAG stocks

I haven't had the opportunity to fire with it yet, but just shouldering it, I like the way it fits in my shoulder pocket, others I've let shoulder it had mixed reviews, but again, for the price, I couldn't go wrong, and I like the way it sits in..Plus the rubber seems to give "just enough" when I pushed on it, looking forward to using it..
