Thank you! The photo makes sense!
Has anyone found any torque values for the MCX stock adapter? In a few other threads, someone called SIG and they told them to snug everything up - no torque values. Someone else said their Virtus armorer's manual say 70 in-lb for the bumper screw (which seems excessive).
To me the buffer adapter has that wrench flat, and its design makes me think torquing to 40 ft-lb ala rifle buffer extension should work? The bumper screw, probably 40-45 in-lb?
I did find all of the other screw torque values (for the screws I could find).
Handguard Link Screw 2400439-R, #8-32, 10 in-lb (as per SIG as well)
Cam Path Insert Screw, 2400180-R, #6-32, supposedly 35 in-lb according to SIG, but that seems like way too much torque for a steel 6-32 screw let alone SS.
Forward Assist Screw, 2400438-R, #4-40, 6-8 in-lb according to SIG, but I saw someone's armorer manual excerpt showing 10 in-lb w/ Loctite 222.
