A kit for rebuilding the Standard Buckling Harness Muzzle Gag with a new or resized ball. Kit comes with the front panel with the ball fitted and riveted on, along with the side straps that are also attached to the panel, and the strap the runs over the head, along with plenty of rivets to reattach all the securing straps.
You will reuse the two straps that run down the back of the head, the two side straps that run around the head (and have the buckle on them as well, as the two captive buckles that attach to the rear straps), and the two straps that cross under the chin and buckle behind the head.
