View Full Version : Loose model 12

What's involved with "tightening up" an old model 12?

It's been well used, but it was grandpa's and I'd like to keep using it.
I would like to get it tightened up a bit before I shoot it too much though, it sat for over 40 years without being fired before I got it.:( (grandma is scared to death of guns:mad:)
It functions fine and shoots ok, but it's a little loose at the takedown joint.

I'm no gunsmith, so I cant help you in that aspect. I however, have the opposite problem. My model 12 is really tight.

I actually have to pull up on the action in order to be able to press the slide release so I can work the action. It also is a hand me down...but has not seen to much use.

Someone will chime is soon and help you out!

Well it is easier done than said. Let me rant first before I try to assist. Just because a gun is capable of disassembly doesnt mean you should! More take down guns have been ruined by constant disassembly than by actual wear. I have owned many take down guns and only disassembled them 1 or 2 times. I have seen a model 12 that had been disassembled so many times the threads were actually worn smooth. Now I will try to help. The model 12 was designed to be adjusted if ever it was shot so much as to need it. First disassemble the action from the reciever. Look at the barrel end of the front half. You will see the chamber end of the barrel is surrounded by a threaded sleeve. This is called the adjustment sleeve. The following script is taken from a Winchester bulletin. quote " The barrel is equiped with an adjusting sleeve threaded on the chamber end of the barrel in the back of the reciever extension which is also threaded on the at the chamber end. This sleeve is adjustable on and off the threaded end of the barrel to produce a tight joint condition between the riciever extension and the reciever into which the barrel screws. The adjusting sleeve is provided with a number of teeth on its outer rim. The reciever extension has a recess containing the adjusting sleeve lock, the slide moving up and down with 3 teeth on inner end which mesh with those on the rim of the adjusting sleeve when the lock is held in place by the lock screw." Next quote, " Turn adjusting sleeve one or more notches counter clockwise to tighten the draw" Whew! Im confused, I would assume you are as well. To summerize, after taking the gun down you should be able to see how to adjust the threads on the barrel end as to tighten the fit between barrel and reciever. Once down I would suggest that futher take down be very limited.

30-30--- I agree with you on take-down guns.

I don't take it down, and I have already adjusted the reciever/ barrel thread extension (guess I could have stated that in post #1), any other options other than trying to find replacement parts or a trip to the overpriced local gunsmith?

Take a look around the net for other sites that have shotgun forums.

Many gunsmithing forms are hosted by very good gunsmiths. It would worth your time to send the Model 12 to someone that works on them all the time.

And yes you will pay for the service, but who ever does the work should be first class.
