I have warne mounts on a tikka T3X. I got my rifle out to clean the other night and noticed a noise that sounded like a screw lose in the mount. It was driving me nuts so I took the mounts off and found a little metal piece that has two screw holes in it that allow the mounting screws to travel through it. It was bouncing back and forth and making noise every time the rifle was moved. What is this piece for and is it necessary? Would my best remedy be to remove it and remount the scope?
