I've recently tried installing afew different pre-fit Sims recoil pads onto my Remington 700 BDL without much luck. The Sims packages say certain models will fit, but they never do. The gun has the plastic butt pad which is ok, but I would prefer something a little softer. Has anyone else had this problem? Would a 'smith be able to install a decent pad on for me?What doi do?Thanks in advance.
