Stuck Choke Tube

[billt460]

Last week I took one of my wife's Beretta A-390's she used to shoot Trap with, out of the safe. It had been sitting in the back for some time, and I decided to get it out and wipe it down.

I ran an oily patch through the barrel, then tried to remove the choke tube, and it was STUCK. I tried some Kroil on it, and after letting it sit overnight, still no can do.

I had bought some of this stuff at Autozone a while back on a whim, and decided to give it a shot. It's basically nothing but a spray refrigerant. I had my wife hold the gun muzzle up, with the butt on the floor, while I sprayed the INSIDE of the choke tube all around for several seconds.

And BINGO, it came right out! I just thought I would mention it because stuck chokes can be a royal pain. And I've seen guys burr up the wrench cuts trying to get them out.

I'm guessing this might work on other stuff, like stuck brake bleeder valves and the like, where heat might destroy rubber seals, O-Rings, and such. I'm going to grab a couple more cans of it the next time I have to drop off my old oil there.

Yall hunt with the gun? Choke tube are one thing that many never remove and clean, if the barrel get cleaned at all.

Is there an 'anti-seize' to use when reinstalling the choke?

A neighbor had an old Browning with a Poly-Choke....one of the few guns I've ever coveted.

No, it's strictly a trap gun. She hasn't shot it for many years. I used Briley grease on it the last time I installed it, and the stuff dried out. I reinstalled it with Loctite C5-A Anti Seize.

It's basically the same stuff Glock ships their guns with, applied to the slide rails.

Yeah, that is where I was going. Of course, choke tubes seal at the threads, but in front of the threads, down the barrel, gasses and powder will make their way up to the threads, likely drying out any oil. Copper based anti seize was what I was going to suggest, or ballistol, as I have had success with it in the past. Sometimes getting the choke tube real tight, actually aids in removal, and your circumstance is one reason why.

Some gunsmiths won't even mess with thin walled shotgun threads, and many times a chase for the threads is more expensive than just buying a new barrel.

Maybe, on the next outing, a part of the cleaning procedure might be immediate removal of the choke tube and subsequent cleaning.

I do not clean shotguns that much, as they dont get dirty by my style of shooting.

Good idea! I also used to be able to buy a freeze spray at Radio Shack for electronic troubleshooting, That would work too.
