The Graco Gracoil Standard Stock Butt Plate is a recoil reducing, compression butt plate with an adjustable tension setting and adjustable pad plate. Adjustments for drop and rotation allow factory stocks to fit any shooter's style. There is no length of pull adjustment, making this standard GraCoil a more economical option. Tension will adjust from 14 lb. to 70 lbs. with a maximum stroke of 5/16" which produce a hardly detectable response time, with no distractions between shots. Moving parts slide on Teflon liners for a smooth and trouble free motion. The GraCoil adds 1" to the stock length, and requires the stock to be shortened in most cases. Its construction is all aluminum and stainless steel and comes complete with screws and wrenches. It uses very little lubrication, and no maintenance is required.
