Re: I'm free floating my sps stock today...
Which SPS? I don't know about the Hogues but the injection molded plastic ones with ventilated forearm and pressure pad at the end will just warp whichever way they choose and touch the barrel again. If it doesn't do that then any amount of pressure much forward of the mag well will make it touch the barrel again. Some report some luck hogging out the barrel channel and installing aluminium rods to stiffen it, I'd give that method a maybe, but believe trying to float it and trying to stiffen it to be a waste of time. To each their own though, good luck, dremel will be fine, I scrapped the pressure pad off mine with a knife, I only kept it for about two range sessions after, it improved nothing.
