How to Install Choke Tubes on a Mossberg 500
- 1). Locate the safety button on the rear of the shotgun, just above the trigger on the topside of the shotgun. Slide the button to the furthest back position, so it is in the "on" position. Point the muzzle of the shotgun toward the floor or another safe area.
- 2). Press the action lock lever just behind the trigger to unlock the action. Visually inspect the action and magazine to make sure the gun is not loaded and that there is nothing in the chamber.
- 3). Remove the old choke barrel from the barrel of the gun, using the wrench provided with the choke barrel kit and turning it counterclockwise. Then slide the replacement choke barrel into the barrel of the gun. Tighten it, using the wrench and turning the wrench clockwise.
