Remington Supercell Recoil Pad for Synthetic Shotgun Stocks fits model 870" 1187 including Super magnum models from 1999 to the present or for non-magnum models from 1997 to the present. These recoil pads are designed for the 12-gauge version only. The Supercell technology has single handedly helped the Model 870 generate up to 54% less recoil than their leading competitors' auto loading shotguns with factory pads. Its millions of tiny Super Cells absorb and release energy over a longer time period to create a more comfortable shooting experience than was ever before possible with conventional materials.
