Another stupid question. I got 2 harris bipod several years ago. My go to is the Harris model S 6-9. I finally broke down and bought a locking lever for the swivel function but now I am noticing after a string of 4 or 5 rounds, the screw that tensions the mount to the sling swivel comes loose. I don't know if that screw is getting worn, needs loctite or if its something else. .
