The Remington SuperCell Recoil Pad is the most efficient inhibitor of kickback energy, providing an amazing 54% reduction in felt recoil over the standard factory pad. Using a complex matrix of millions of SuperCells, the advanced polymer construction harnesses and releases energy over a much longer time period. Rearward force of your gun is reduced from a kick to a gentle push and muzzle travel is diminished, resulting in the softest shooting experience possible. Fits models 870, 1100 and 11-87 (2004 or newer) including Super Magnum models that came with the R3 or SuperCell Pad as original factory equipment. Designed for 12 Gauge only. Will not be a "perfect fit" for models that did not have the R3 or SuperCell Pad as original factory equipment.
