Win Model 12 barrel tightening

Labradorian · Nov 30, 2020

I have an old 12 12 ga (1920's fore grip)that I believe came from my g-pa. I'm doing some resurrection work on it and besides grime and rust, it has the 'wobble' in the barrel / receiver extension. I am aware of the adjusting screw in the receiver extension that gives a bit of clocking of the barrel lock, but. umm, ~cough~, a long time ago, so has someone else. To make a tight fit when assembling the barrel on the receiver, the bead ends up at about a 2 o'clock position.

The parts diagram shows an adjusting sleeve that mounts on the end of the barrel that the receiver extension threads on to. On mine, I am not getting the receiver extension to unthread. It turns some but there is damage to the threads cause I guess my g-pa was a ham handed idiot. Anyone ever replace a barrel or bushing on a mod 12?

There were different bushings available to fix your problem. The problem is finding one, they have been out of production for so long it's getting difficult to find them.

Here you go, instructions and the parts can be found here, took about 30 seconds to find.

I'd seen some various bushing sizes searching around but not this kit.

Yeah, nah, $200 for a kit is not an option. A $30 would make this gun worth about $35, maybe $40 if the buyer was blind.

I still haven't managed to get anything to unscrew either. ETA: disassembly success.

Found a cracked chamber ring. The barrel and bushing have an uneven surface to index on.

I can see why they quit shooting it and I'm happy I never tried.

I would buy it from you sight unseen, let me know if you want to be rid of it.

I did manage to get the receiver extension and barrel to fit somewhat properly indexed on the receiver, when following the instructions.

Amazing that.
