What sort of mount did the issued M-14s use?
Given the trouble everyone else seems to have with scoping it, maybe their approach works better.
there were a bunch of single thumbwheel mounts back then - i still have my s&k- i can't remember all, but i think brookfield was involved, and some others- typically they all had half-rounds and ledges that line up with the slots in the receiver- the rear end wasn't fastened down so that if something happened , you could strip the scope off the rifle and still have a normal m14- also these "problems" show up as a result of 1 wanting tighter groups,or longer ranges
2 back then all mounts were made of STEEL- whether fabricated in house ( rear echelon) not aluminum- that's where the "problem" lies
steel expands at a different rate than aluminum, and it's that expansion that causes the screw to loosen- screw loosens, plate move out of the mortice and tenon joint, and now your shot is lost- that's why that thumbwheel is so big- you'RE supposed to CHECK IT BEFORE THE SHOT- when you're doing your "hand inspection"- if you don't know what that is, ( typically it's done in the dark) you run your hands over the entire rifle, feeling for things that are loose that should be tight- the t.o.s used to take all the rifles in barraks, monkey with them, then let us back in, turn the lights out and we had to 'inspect and verify-then you stuck your hand up andthe to came over and you told him what was wrong, and what you did to remedy the situation- you had 5 minutes to complete the task-personally i question the advantage of the replacement charger clip and screw arrangement- but these guys with the 3 points or better mounting system also want CONSISTANT groups at 600, to 1000 yards, which was outside the typical m14 mandate, even with scope- remember, nobody thought about the bipod thing either , and if you did get ahold of one , it was off a m14a1 that was rtu'd - somebody had stripped it off for "pogey bait"
also the stocks were standard profile, no cheekrest for scope- you had to crane the neck to use it
