Three step technology makes the LimbSaver recoil pad one of the most effective recoil pad systems available. Constructed of NAVCOM, a proprietary material (noise and vibration control materials) this pad ABSORBS shock and reduces vibration. It redirects energy using specially designed internal mushrooms, utilizing DTMS (Decay Times Modification System). Recoil is directed outward instead of straight back into the shooter's shoulder. Internal atmospheric air chambers allow the pad to COMPRESS under recoil, acting as a shock absorber. Quite simply, the Sims LimbSaver recoil pad is the best recoil pad on the market. Available for the T/C Encore, Omega and Black Diamond Muzzleloading Rifles.
