This piece allows you to pump your gun and load the bullets into the carrier. If you need to clean your threads out where the forearm screws attach. For a better quality piece look at wp1 wop.
Since many of the action arms break in the middle, we have made a repair where the bar transitions into the tube. A layer of solid brazing has been added at the junction of the arm and the round portion where the wood forearm is attached. These repairs are usually hidden and not visible when the gun is assembled.
