The Speed Mount recoil pad from Limbsaver uses the same recoil-absorbing technology as their pre-fit pads, but can be ground down to fit your stock for a perfect fit. Made from a proprietary material for maximum recoil and vibration reduction.What makes the Speed Mount different is the unique shape. With a sloped heel and toe design the pad gets into position on the shoulder smoother and faster than a pad with sharp square corners like a lot of modern recoil pads do.
