The Killer series stabilizer is equipped with our original patented SandTrap technology. Acting on the same principal as a dead blow hammer, the sand mixture shifts on the shot eliminating hand shock and vibration. Unaffected by temperature, this technology works the same in 90 degree temperatures as it does at zero, never failing you in the field. New for 2020, our exclusive VOID rubber dampener reduces vibration further, making the stablilzer even more effective. Threaded to accept weights.
