My optima choke on my 391 teknys gets loose after just one round of trap. Any one know a good way to make sure it doesn't do that?:confused:

Thanks
 
I have never had the problem with my 391, or any of my guns for that matter. I was told that it is better to use a grease on the threads, as opposed to oil. It was suggested that the grease would support the threads a bit better, and it goes tend to provide some adhesion.

It works well for me anyway.
 
I would never put anything but oil and maybe even grease (vasilene) on the threads of my choke tubes (never put plumbers tape or locktite on them)

after each station i alway turn my tubes, I guess it is a force of habit, especially in sporting clays when i'm contantly changing chokes.

I would just turn it really tight and hope if you are that worried about it. After ruining a few barrels to overtightening chokes/ not always taking them out, I am more than happy to give it a tighten up after each station.

Just my two...
 
Had the same issue with the 391 Optima extended chokes. I just gave it a turn to tighten it every once in awhile. The mickey mouse wrench that Beretta supplies with the extended tubes is useless.

Stay away from plumbers tape. That can only lead to trouble if the barrel gets heated up.

Yeah it's an extended choke tube. I just don't think it should require any turning after just one round of shooting...

Almost everyone I have ever seen with extended (and sometimes flush) tubes, have to adjust them often.
A little sand works wel but I wouldn't reccomend it!

Maybe a thicker grease is the answer, I just live with the fact that i am constantly checking my tubes, and more often than every round too, like every 5-10 rounds.
 
I know some guys automatically give them a check after each shot - but that's a little paranoid even for me..... I just got in the habit of checking after each station. No big deal with extended choke tubes. It's sure easier than checking flush chokes!
 
A light coat of your wife's clear fingernail polish on one or two threads (not too much). I use it on all my scope bases and rings.
 
been down that road before

the reason for this could be one of many things. you may have shot with the tubes loose thus creating play in the threads, also possible that at one point they were overtightned. try to borrow somone elses tubes to see if they snug in your thread. if so you can remidy this with some after market tubes. if your threads are damaged on your bbl then you have bigger problems... just a possibility. message me private and i might be able to help you.

Do you own a 391 with extended Optima choke tubes? If you did you'd probably know that they frequently come loose in this manner. As do Benellis with extended chokes. FWIW, I've also seen Brownings with extended chokes do the same thing.

Aftermarket chokes don't solve the problem either. I have a set of Teagues for my 391 and they come loose if not firmly tightened. Also, a few years back I had a complete set of extended Beretta replacement chokes made by Briley. They fit the 682 firmly and never came loose, would come loose in my 390 and wouldn't fit a Beretta 687 owned by a friend who tried my chokes when he forgot his. Not all manufacturing tolerances are precise.

With my Beretta 391 I use Briley choke tube grease to keep the tubes seated. I also dumped that crappy Beretta choke tool and use a Carlson Choke tube wrench to firmly tighten the choke tubes in the gun.

I have had the same issue with my 391 and Briley extended choke tubes. I run a bit of Crappy Tire spark plug Anti-Seize crayon on the choke tube threads and it cuts down the retightening dramatically. Heat certainly isn't an issue, and they come out real easy when it's time to clean.
 
I have 3 Berettas, all with Optima extended chokes ( + a few aftermarket OEM Optima chokes in different constrictions ... about 25 in total ) THEY ALL WILL LOOSEN WHEN SHOOTING ... the cleaner they are, the more prone they are to loosen-up. A choke that's been in a particular barrel for a while, say a Lt. Mod left in for a whole round of Sporting - likely won't be loose after 40 or 50 shells go through it ... in fact, it may be a little sticky to remove.

I routinely check the chokes for tightness after each station or two ... sometimes they need a little snugging down, sometimes not. What can it hurt. After a while, it's just automatic.

A little oil on the threads wont hurt ... no teflon tape, no grease.
Clean the threads when you clean the barrels/chokes. Even with "premium"
shells, the chokes will load-up with plastic residue that needs be removed occassionally.

Hey ! The Briley on my gold is loose too . I understand better the purpose of the extension .

I had a similar problem with a Browning A500 but everything was getting loose on that gun . It doesn't mean much . Paranoia did affect me quite a bit : I was using the rim of a cartridge as a wrench every 5mn. I didn't have to do it for long. I traded the gun for a Lightning . I never had a problem with this one.

When I think of it, I have seen that problem only on semi autos. Right ?
 
choke

Go to Cdn Tire and get some "DOOR-EASE". It's a stick lub that will prevent chokes from coming loose and eleminated a stuck choke. Apply a small amount to the threads- great stuff'
Luck. J
