Need help to ID this stock

[crazy merc]

Hi
I am looking for help to ID this stock. I narrowed it down to possibly be from the Mossberg bolt action shotgun. But I am not 100% sure. It might be 50 to 60 years old and it does not look like its being used much or at all. Plus it comes with that black plastic piece, which looks like a hanguard. But its slides too easy and does not seems like it attaches somehow.
Any help is much appreciated. Thanks

The plastic finger groves sure look mossberg

Awesome. Thank you. That thing looks like Soviet WW2 anti material rifle
