I know....I know but it’s not mine. My buddy hid some of his stuff when he was splitting from his psycho wife and forgot about his Mossberg 935. I’m diligent about maintaining my equipment and using choke lube/ant-seize but he’d just as soon go buy new. I want to salvage this POS and was wondering if there’s any tricks? I’ve been soaking it with PB Blaster but so far no luck. I’ve shot several rounds of trap hoping to break it free but no luck.

What do you guys suggest? Thanks in advance. 👍

Never had one that wouldn't give but they tell me sticking it in the deep freeze may break it loose. Worth a try.

Go to the hardware store and get an easy out, It's rather large, lie 3/4 inch. Secure the barrel in a pipe vise or between 2 pieces of soft wood, the barrel will want to spin and you don't want to torque it, obviously. Tap the easy out in a and it ]'ll spin the choke out - I've only had one or two chokes tubes that were salvageable but every barrel wa ready for a new choke. Chokes are thin walled so don't "drive it it" just tap until it stops then spin it out.

Kinda the last resort though. Feels like a bigger victory if you can save the choke tube.

I would try several cycles of cold/heat with soaking Kroil in between.

A trick I used to remove the barrel nut on DW revolvers was to pour boiling water through the barrel. It might loosen the threads.

Buy a can of Break Away. invert the barrel in a jar of it for a few days, good choke tube wrench should remove it. If not, the you'll either need a pipe ez-out or find a reputable smith

And when (not if) all the above fails, just cut the sumbish off and reface...

My brother made a choke wrench that he hooks up to his impact driver.

I have the 100 straight tool, it's taken out chokes even gunsmiths said were not coming out. That said, the overbored barrel on the 935 presents a challenge since i do not think I have a collet to fit those chokes

ATF/Acetone.

A machinist magazine did a test of a pile of different penetrating oil products.
ATF/Acetone beat them all, including Kroil.

Soak that puppy, try to keep it ait tight, acetone will evaporate off.

You could maybe get a jump by heating it up a bit before you soak it.

The EZ-out thing?

Last resort before a hacksaw.

Soak in ATF/Acetone or Kroil and after wiping off if it doesn't come out try ice in the choke and heating the barrel lightly then use the best tool you have. The expanding rubber type of tube tool has worked for me on stuck tubes. There is a lube that I think has copper and moly in it made for choke tubes, it never dries out.

You can make an extractor with a couple rubber lab type stoppers on a large bolt. The bolt will allow you to use a longer breaker bar for leverage. Hold the stoppers on with a nut and washer use two nuts and a lock washer on the bottom end.. Put it in the choke where you can screw down the upper nut tightly. Then use the breaker bar on the bolt head. Wash all the solvent off with brake cleaner so it is completely dry and the rubber can grab the choke first.

Stupid question, but it needs ask.
Around here, most 835's are Turkey guns, nothing else.


Does he really want to change tubes, or was it just a lets take it out deal?

Is it a big deal if it stays in?

Choke tubes need lubed and anti seize should be applied when installed. Dry does not work. You gall steel to steel. No penetrating oil will work.
