Picture:
Background: When I bought this it was painted brown. I took the paint off and there was no shellac left. I went the tung oil route. Recently I discovered this crack. None of the numbers match but it has it has a nice bore and shoots well enough.
What should I do?
1) Nothing, Mosin is fine,
2) Replace the stock with another one,
3) Attempt the repair myself with a 'Stalingrad screw',
4) Do something with glue, or
5) Go see a pro.
