Is there a safe way to lock extened chokes on my semi auto, they tend to get loose after a few shots. I tend to use the flush chokes which have a key and stay safe.

Thanks Alan

Are you greasing the chokes before you screw them in?  Perhaps counter intuitively a touch of good choke grease helps to prevent the chokes loosening by themselves.

Beyond that a tapered choke key as mentioned above is an option.

You can screw them in and out with a cheap webbing oil fillter removing tool. and a ratchet. You can make a leather one and wrap it on to itself they will undo like that with nothing more than a pair of mole grips to grab the leather. no damage because its just the strap around the tube no crushing or scuffing from and grips etc.

IF it is a Teague extended choke, it may just be the choke. I had a Teague extended in my Beretta auto and that kept coming loose after every 6 or 7 shots. Changed it for a Briley, problem solved.

thanks for your coments, very helpful. the choke that gets loose has no slots for the key.

i just found a tube of copper multi purpose grease for disc brakes, i guess that a spot of that wont hurt.

i will make a removing tool shortly.

I've found that 'Copaslip' grease which is used on exhaust studs etc on cars is great for helping chokes stay tight and being intended for ultra high temperature applications it is ideally suited to the task and has a certain 'stiction', a resistance to working loose quite as quickly as normal grease compounds.

Which chokes are you using ? (briley, teague etc).  I havent found an extended choke that doesnt come a slightly loose over time, apart from my Mullers which I use on my Beretta 682.

There have been a number of sensible options to solve the loose choke issue. Then there is this one. There are a few reservations:-

1. Using a ratchet and oil filter strap - far too agricultural and oil filter straps are made for a larger tube. I would question the grip.

2. Leather and mole grips - despite the suggestion they will do no damage, you would run the risk of deforming the tube.

3. Rather than carry a small tapered key, specifically made for the job, you could carry an oil filter wrench, a ratchet, a leather strap and a pair or Mole grips. Perhaps you could store them in a top box or roll cabinet, to lug around. 😄

Classic.

Any kind of grease stops them rattling loose

Mine are finger tight (on a Beretta 682) every now and then I lift the barrels and nip them up, occasionally (rarely) they are loose, just by an 1/8 turn and I still miss  :)
