The shock eater uses a Nano-Poly insert to absorb recoil and minimize shoulder fatigue. This product has been tested by ourselves as well as several fellow shooters and works amazingly. It minimizes the amount of recoil that is felt by the shooter to almost nothing. This product is an outstanding addition to have. It is soft, doesn't create a bulge, and has several inserts to maximize the comfort level of the shooter in order to improve accuracy and consistency! We highly recommend this new product for any shotgun shooter.
Plus it fits perfectly underneath our butt stock covers!
