M512 Disassembly Question

[jacobtowne]

Mine is an old, pre-SN M512 Sportmaster. Occasionally a cartridge will not rise high enough to be taken into battery by the bolt face. I suspect it needs to be taken apart and given a good cleaning.
Where can I find disassembly instructions?

There are several good books on assembly/disassembly. A used book store or a book table at a gun show will probably have one. The Gun Digest rimfire book does not include the 500 series for some reason, but the NRA Firearms Assembly 3 does.

Thanks for the reply.
I have the NRA manuals, old ones though. The shoulder arms manual includes the M514, but this is a single shot with a bolt-head safety, quite different from the 512.

Mine is dated 1980. Page 128 shows the 510. The next page shows the 512. The 514 is on pages 130 & 131.

Good luck. They aren't too complicated.

That's why. Mine is 1972. Guess I'll have to look into updating my antiquated library.
