My Beneli Recoil Reducer finally came in at my local gun shop. I brought it home and there were no instructions with it. I was only able to secure the bracket with one screw as there was no way to get a screwdriver in to secure the second screw. When I dropped the mercury filled tube into the bracket there was a gap of about one to two inches left in the bracket. This means that the tube will slide up and down with an inch or two of play as I move the gun around. Know, there was a piece of black hose about five inches long that was sitting inside the bracket when I opened it from it's original packaging. I'm wondering if I am supposed to cut a piece of this hose to fill the gap in the bracket. Anybody have the answer?
