My purple Loc Tite is still holding. I put small marks on the screw head and frame so I can see if there is any movement while shooting. I torqued the screw to 40 in/lbs. I cleaned the screw and hole with Acetone and put the Loc Tite on the starting end of the screw ran it in , backed it out and then back in and torqued it down. Let it set for 24 hours. The rail mount screw came lose yesterday. lol
