Original Hydro-Coil Dockwiller Shotgun Recoil Reduction System "Jack-Back"

Original Shotgun Recoil Reduction System The Dockwiller Hydro-Coil System "Jack-Back" If you have one of the 1000s of HydroCoil Stocks Built, we have re-introduced the Hydrocoil unit to fit your existing stock. What is s hydro-coil system? It is a gun stock with sliding outer shell which supports the pad, and a recoil reduction unit called a Hydrocoil which compresses when the shotgun fires. A beautiful Dockwiller Hydrocoil is shown in the photo section. The units are AIR charged and reduce the recoil about 80 plus percent. Our new units can be charged with a portable air pump shown. Trigger Sports and the Dockwiller shop now stock the replacement parts to repair your unit. Please call us at Trigger Sports for additional information about the new units and the repair service. Jack Dockwiller will fit the units to your Hydro-Coil Stock if necessary. Please call Trigger Sports for additional information or to purchase or schedule an installation appointment.
