Graco BreaKO Mercury Recoil Reduction System Beretta 390 Magazine Cap Mount Steel Blue
BreaKO recoil reduction systems are designed to reduce recoil acceleration, muzzle bounce, and minimize gun movement during firing. The quality of these units is evident in the design and workmanship. Mercury is used in these units because of its natural ability to absorb and dampen shock. Results are less fatigue, better concentration, higher scores, and comfort-able shooting. All steel construction, "mercury" filled, permanently sealed and ready for installation.
