1891 Milled Mosin barrel band

[CleptoVapor]

Just picked a beautiful Finnish Mosin Nagant yesterday one rather large problem is the barrel band screws have been snapped. Is it possible to repair the screws or would anyone here know where to find replacements?

The barrel bands screws on the M91 are left hand thread. They are commonly found snapped off because of this. You might be able to extract the ones in the bands, but finding a left hand thread die in the correct tpi and pitch (especially since they are metric) to make new ones might be hard. Liberty Tree collectors sometimes comes up with the whole band assembly, but not often, and not cheap.

I had the same problem. Take a look at apex, it took a couple returns to get one that the retaining flare on the screw was still good on.
Depending on condition, a half-assed polish and cold blue made my band match the half assed arsenal blue of the rifle.

Looks like all the big sites (liberty, sarco, apex, etc...) are sold out on any of the bands. I found one for sale but it's in Australia and they're unable to export it -_- sadly

 

[entropy]

Yeah, not surprised. Even before the craziness began they were scarce. It's a gun part, you'd figure the Aussie Govt. Would be glad to get it away from them.

Mabey you could drill & tap to a RH thread?

That's going to be the route I have to go if I'm unable to find a replacement right now I've managed to get it to hold just enough with that it's staying together

 

[CleptoVapor]

You would think that. I tried to buy a couple barrels from them last year and they refused to even try to work with me or the importer I go through.

If you have access to welder you could fill the hole and recut the threads. Check with McMasterCarr on the left hand drill bit. They have a very good selection to choose from.

The threads are still in good condition. The problem is the unthreaded half with the mushroomed end is snapped off.

You have two separate issues. Broken screw extraction is the first issue to solve. If you can get them out without damging the threaded holes, then think about having proper LH thread screws made. Any decent machinist can make them either from scratch or by threading screw blanks available from Brownells. Lots of hobby machinists do that kind of stuff on a semi regular basis.

The screw is actually a RH thread, but you take off the band by tightening it, which of you don't know that, that's how they break. Most likely, the screw broke on the narrow stem or mushroom that holds the retaining washer.

Mine snapped on that narrow end unfortunately and that retaining washer has been lost to the ether.

Well seeing it won't clamp as is, why don't you find a longer screw that fits. Then drill out the mushroom side so the screw passes through and threads into the threaded side. You'll have a working barrel band. I doubt anyone will notice and I won't tell if you don't. Good luck.
