INSTALLATION INSTRUCTIONS: This recoil reducer consists of two pieces, the black recoil reducer, and the silver mounting piece. To install, first remove the recoil pad from the buttstock of your gun. If you need instructions on doing this please see the video HERE. Next, remove the stock bolt and washer. The washer will not be used while the recoil reducer is installed. Instead, thread the silver mounting piece onto the stock bolt and reinstall the stock bolt in the gun. You will now be able to screw the black recoil reducer into the silver mounting piece. Reinstall the recoil pad and installation is complete.
