Hey fellas, so I've got an 870 Express Tactical that I'm generally really happy with, however the chokes will come loose after a few shots. It happened with the Tactical choke it came with and now that I've switched to imp cyl and modified chokes (tightened with a Rem choke wench) it continues to happen.

Is there a secret to keeping them in place? Do you put anything (grease) on the threads?

Thanks in advance
 
I have an 870 I have been shooting for over 10 years. I don't put anything on the threads and I don't even tighten the chokes that much. Never had an issue. I wonder if some of the barrels are slightly out of spec?
 
The guys who say they've never had a problem have just been lucky.
I never had a problem before either with any shotgun I ever bought, maybe 20 of them came and went over the years.
I've changed nothing about how I clean and prep my guns.

Having said that, the last two shotguns I bought have this affliction where the chokes come loose after a few shots.
Interestingly both of these guns have extended chokes, which I'm beginning to think might be part of the problem.
One is a Beretta A400 and the other is a Rem 1100 = two different manufacturers = same problem.

Now, in an attempt to cure the issue, I did clean the Beretta choke threads with brake cleaner and degreased the chokes too. I put the choke in using some anti seize compound (which may seem contrary to logic, I need seize not anti seize right?)
Anyway, the problem seems to be getting better with the Beretta. Is it the anti seize or just that I put more rounds through it and blasted some crud into the choke threads.
Personally I think its the crud.

All I can suggest is that you clean the threads real well to remove any lubricant, and then just put a light coat of anti size.
When you put the choke on, don't tighten it much.
I mean leave it just barely finger tight.

The reason I say just barely finger tight is to invite the crud into the threads when you shoot it.
Keep an eye on the choke - re-tighten it as needed.

Eventually you'll get enough blow by into the threads that it will stop coming loose.
After that I think the problem will stabilize.

Another idea...
I saw someone post somewhere that you could try painting the threads on the choke with nail polish. After it dries it will help bind the threads.

I have one more thing you might want to try...
Crank the choke on fairly well, I mean don't over tork it, but make sure it's firm.
Then go shoot it, and each time it comes loose, tighten it again, real well.
I have a feeling this could help "Seat" the choke in case the surfaces are not netting out well, possibly due to some sort of concentricity issue.

If anyone has a better idea, I'd sure like to hear it.

I've owned several shotguns with chokes... all of them work themselves out (I have never owned a shotgun where the choke stayed put.); most recently my Benelli M2 choke got very loose after only 1 box of trap loads (shot quickly.)

I'm going to try a single drop of blue Loctite to see if that prevents the choke from working itself out. I can report back when I get my findings.

Cheers~
 
I have a 870 Supermag and I haven't had an issue yet, even shooting slugs. I periodically check them to make sure they are tight. My old Browning BPS on the other hand would come loose after one round of trap. Clean the threads good and oil has worked well for me.
 
Thanks for all the input. I put a bit of Teflon tape on the threads, and hopefully I'll get out tomorrow to test it out (weather permitting). I think I'll also pick-up some Gorilla Grease to try out, next time I'm by Cabelas.

A little dab of RTV silicone works well for keeping threads in place and provides anti-seize when you want to change them out.
 
never mind
I think I'm getting warm

Invite crud to form in super fine choke threads?? Um no. For those having issues, get some copper-kote anti seize. It'll take the abuse of being inside a bore whilst keeping those threads tight as well as easy to disassemble.
