1. Unload firearm and remove any ammunition from the magazine tube, check chamber and lifter visually and physically, engage safety. Ensure work area is clear of ammunition. Treat every firearm as if it were loaded.
2. Tools required:
Phillips Head Screwdriver or drill with Phillips head bit.
3. Remove 2 screws securing the factory butt pad from the rear of the stock.
4. Fit and align the A300SAM on to the butt pad so the molded extensions of the pad insert and pass through the cutouts in the A300SAM. The bend and sling attachment area should be arranged to extend down the right side of the shotgun, and the contours of the A300SAM should match that of the stock.
5. Use the original screws and securely fasten the butt pad and A300SAM assembly to the back of the stock. Use caution to ensure the screws thread in properly and do not overtighten or strip the screws inside the stock.
