Browning's Reactar Pad (Recoil Action Arrestor) absorbs recoil on the inside of your vest, jacket or shirt without altering its appearance or increasing your length of pull. It is only 1/3" thick, lightweight and flexible so it forms to your body. It uses a patented substance called Beta Gel that, in tests, reduced peak recoil up to 49%. Many Browning shooting vests, shirts and jackets have an integral shoulder pocket to fit this pad.
