The Hunter/SGA OEM Butt-Pad Adapter allows the user to replace the factory recoil pad on Magpul SGA Remington or Mossberg Shotgun Stocks as well as the Hunter 700 Stock with a Remington 870 synthetic-pattern butt-pad of their choice (not included). By utilizing the original spacers, this adapter retains all the functionality of the Hunter and SGA Stocks while providing for additional butt-pad options. RSR -
