Hyskore® Dangerous Game™ Machine Rest

The Dangerous Game™ Machine Rest uses Nitrogen filled compression dampers to absorb the recoil. If the rest is firmly anchored to a solid bench, the gun will return to battery (+/- 3 MOA) after every shot. Since the compression damper absorbs the recoil, in a manner similar to your shoulder, there is no need to worry about damage to stock, bedding or recoil lugs. This is in sharp contrast to other products that require extensive realignment after each shot and offer more resistance that is manageable for the structure of the gun. Each Dangerous Game Machine Rest is equipped with one light, one medium and one heavy, factory calibrated, compression damper. There is no equal for sighting in or load testing. By using the remote trigger release any human induced motion contamination is eliminated
