Help identifying mag 👍

[(M)]

I found this mag in a box I recently inherited. I’m not sure what caliber it is or what it goes to. Any help would be appreciated. Thanks ODT

The common term for this magazine is a "duck-bill mag" and it only works in the SKS after you have disassembled the rifle and removed the factory 10 round internal magazine.

If I remember right these can be difficult to load in the SKS unless the bolt is open.
( at least mine would sometimes not lock in place with the bolt forward and closed.)
