flyinverted Posted May 28 Share Posted May 28 What is the most likely thread size for a frame mounted optic mount? I realize there are probably 5 different sizes, but one has to be more common than the rest. Link to comment Share on other sites More sharing options...
Haywizzle Posted May 28 Share Posted May 28 5-40 is very common. Usually 1/2" long, trim excess. You will need longer if you have a thumb rest. https://forums.brianenos.com/topic/249042-screw-size-for-optic-mount/ Link to comment Share on other sites More sharing options...
shred Posted May 28 Share Posted May 28 Old school guns used a lot of 6-40, 6-48 & 6-32 as well. Are you trying to match something or drill new? Link to comment Share on other sites More sharing options...
