Hello - I have a 40 year old wood M77 .270 that the rear trigger guard screw fell out of. Can someone please tell me the torque specs for both the rear and front screws? I was going to loctite the rear back in and was also thinking about taking the front screw out and loctiting it back in. Also not sure if I should mess with the front screw since it’s been in the Gun for over 40 years and never given me a problem? Thanks!!!
