These recoil devices operate in the same manner of a soft touch system except the front of the comb cannot extend beyond the original comb position and interfere with the thumb or upper palm. It has 3/4" of recoil into the stock and a 4-way adjustable comb that moves with the recoil. It operates with a spring-actuated piston and has a set compression based on the spring pressure. Using a different spring inside the piston cage can change the compression. The standard spring in this system works very well with what we consider a 16 yd load (AA, 18.2 clays, 1 oz) up to the AA super handicap. This system allows the gun to recoil back while the comb stays in position with your cheek. The comb has a total of 3/4" cast adjustment (side to side) and unlimited height adjustment depending on the posts ordered with it. Price for the hardware and custom fit installation to a stock is $395.00. Polishing was $55 extra. All stocks have met the ten-day turnaround or less from the time that we receive it and have it ready to ship out.
