I just recently bought a used Bowtech Guardian. The bow already has very little hand shock, but it did have some. So I installed a MeanV suppressor. I new these style suppressors worked, but I didn't know just how well. The bow was completely dead in the hand after installing the MeanV. I'm very impressed. I will never buy another bow that either doesn't have factory suppressors installed or a threaded hole in the back of the riser. Thank you Dan for a GREAT product!
