For years I have been bothered by the forearm sling mounts rotating losely. I have always been afraid to tighten them too much and have just put up with it. I had a BAR once that was shooting god awful groups and I finally attributed this to that mount being over torqued. I don't know if this will be the same with a 700 on a HS stock but I thought maybe somebody here had an old trick to keep them from rotating. Maybe some kind of locktite?
