TO ATTACH BUTTSTOCK / PISTOL GRIP:
Before making any buttstock/pistol grip changes, move the safety button
fully rearward to the “ON” (SAFE) position and visually and physically
check the chamber, elevator, and magazine tube to be certain the shotgun
is unloaded. Also, be sure to keep the action open and the muzzle
pointed in a
safe direction. Refer to your firearm’s owner’s manual for
additional safety and functional information.

buttstock/pistol grip forward on the adapter (Fig. 13b) and strike the rear of the
buttstock/pistol grip with an open palm to fully seat it on the adapter.
