New manners LRH stock with their arca rail and RRSOAR anvil 30 ball head. Doesn't clamp tight enough (gun will slip out). Had previous ARCA rails that clamped in securely with no issues. I don't see any way to increase clamp tension (like say an atlas bipod setup with adjustable nut). Any thoughts? Can't see to find anything in the manual for the tripod to help. Can't post video for some reason. Thanks Brian
