Stubborn choke tube help

[Realtree]

I have a choke tube that does not want to come out of the barrel of my Rem 870, does anyone have any suggestions on how to get a stubborn choke tube out without harming the barrel?

Thanks in advance

i had the same thing happen, my choke tube expanded in the barrel and i ruined 2 choke keys trying to get it out, just use lots of oil and a quarter as your choke key as its less likely to strip out like the choke key did, use pliers on the quarter for better leverage. it is really a pain in the butt and i dont think it hurts the barrel in anyway

if your choke tube is hung up do to not being removed in a long while I would soak it good in some break free or wd40 (a penetrating oil) and let it sit over night.. then use a quarter or something that can take some tork'n and twist er out.  if it's from a bulge or some sort of malfunction, then I would tt a gunsmith and see what they can do.

what I've done before is taken the barrel off the gun, and set it muzzle side up over a piece of cloth on the floor, sprayed the choke tube with WD-40 and let it sit for an hour or two and it usually comes out.  Another option would be something like hoppes solvent instead of WD-40

I've taken the barrel off and put the end of it in a can of diesel fuel overnight.....

If ya got some around, works just like penetrating oil.

I sprayed it real well with some Knocker loose penetrating oil and will let it sit overnight and see what happens. I bought the gun from a friends Dad several years ago and have never used this barrel yet. I was surprised to find a choke tube in it when I pulled it out.

Thanks for the great suggestions everyone!

Or kerosene, which is in diesel. WD40 is made mostly of kerosene. If all else fails.... take a torch to it!

When you do get it out, give it a little shot of anti-seize or get out the muzzle loader bag and smear a little breech plug grease on it before putting it back in. Next time it might pop out a little nicer.

Soak it in Kroil Oil for a few days.  Best rust buster out there.

did ya get it out???

Be careful with "break free" and WD-40,this stuff will take the blueing off,and if she's that tight you either over tighten the chokes or its cross threaded,as stated about for tough chokes,"needle nose pliers and a quater and a little more elbow grease and she should break free.

[Bufflehead]

 They don't have to be over tightened or cross threaded. They can be swedged in by shooting large BB's of steel shot or heavy shot. They can also be stuck from corrosion.

 I'm telling you this, Soak it in Kroil Oil for a few days. It's the best there is at loosing them from corrosion

Whatever the case is "she's locked up" so don't take any chances once you break the choke free,clean both threads up,oil and re-insert and check the pattern board to make sure she still shoots straight.

Update: I finally ended up getting the choke tube out.   

I let it sit for the week with Tri-Flow lubricant in the barrel (with a rubber plug in the end to keep it in there) and then got ahold of a Remington choke tube "speed wrench" that engages all four knock outs in the choke tube instead of just two opposite sides and she came right out.

Then, I cleaned the barrel up real good, re oiled it and will be doing some target shooting in the next couple of weekends to ensure it is still shooting straight.

Thanks for all of the great suggestions.   

I had bought the 870 Express combo with this barrel from a friends Dad and didn't think at the time to check this barrel for a choke tube already in it. I have had the gun for about 15 years and this will be the first time I have used the bird barrel, so I'm pretty sure it was just a matter of this choke tube being in there for so long is why it was so stubborn.

Good to here,yeah 15 years I'd say she was well sealed."Tri-Flow" is a great all around lube for shotguns and it won't "soften" or "discolor" the wood on wooded shotguns,the oil is highly recommened as the only oil for the "high-end" shotguns in the competition shooting world,this coming from Perazzi Italia,so keep plenty around.

I'll have to check out that tri flow.. never seen it before.
