No bubba here, just keep moving.

I have a nice old M91 barrel in immaculate condition but with a crunched receiver. First thought is to find a junker Mosin with shot out barrel which I can turf and utilize the receiver for my barrel. New life for grampa Mosin.

Any issues with that? Would there be any obstacles or problems outside of the usual on an old gun? I assume threadings were pretty standard and since the Finns seemed to do just fine re-working the old dogs for so long.

Any comments, questions or info would be much appreciated.
 
I havent tied it yet, but the barrels are supposed to be a real ##### to come off. As far as I know the threads are all the same. My barrels with crushed recievers will be on their way soon.
 
I have only debarreled one, wasn't a problem. I have no idea whether they are "timed" or not. Wouldn't be surprised if they are.

There is an easy way: make a relief cut on the crushed receiver side very close to the barrel's abutment to get some of the pressure off. The same is often done, on the barrel side, when pulling a bad barrel off a good receiver.
Use of a lathe can be real helpful.:)
PP.
 
Good answers but......

With "garden variety" Mosins with VG+ barrels going for $100-150, the expense of buying the Mosin with bad barrel, then the barrel, then paying the gunsmith, makes the proposition dubious from a financial point of view.

If on the other hand, the gun is "collectible", rebarelling will improve its shootability, but reduce its (collector) value.
 
I appreciate the financial point, I would be paying more for all the work than the whole thing usually goes for. I am willing to do it regardless however, to have a good working Mosin with a better barrel than I have seen in a long while.

The barrel with the crunched receiver is 'collectible'...that is if the receiver wasn't destroyed, so wouldn't it be better functional again?
 
That's just me thinking with my pocketbook and not my heart.

I have many times spent more than made sense because I just wanted to - for example "un-bubbafying" an old Carcano. Got a lot of satisfaction out of it, and every time I shoot it I recall how I got the barelled receiver one place, the stock works another and the bolt yet another - I have about $150 in a $100-$125 gun.

Most of the fun in collecting is in the chase after all, and so it is in shooting if you have fixed it up yourself.
 
Cool, thanks for your insight Andy, it is something I would like to do if only to consider having 'reclaimed' some more history than I can do more with than look at and shake my head.
 
I got the impression when I picked up all these parts that the guy had put the receiver in a press of some sort and just squished it together. I know my terminology isn't 'official', I just don't know what else to say. :p
