re: Choke tube stuck Update

Put it in the jug of penetrating oil (or WD-40) -- upside down, just like the other guys said.

It'll come out -- but why a vise?? Put the barrel in the gun, hold the gun firmly and use a choke tube wrench to loosen the choke (after 24-48 hours in the oil.)

Just be patient.

AFTER you get it out, clean all the threads (on the choke tube and in the barrel), then put some grease on there. Briley sells choke tube grease, and so do several companies that market gun lube products.

The grease that Briley sells is a lot thicker than the stuff you'd put on a fishing reel. And it's obviously thicker than the oil that Beretta recommends. But it's thinner than wheel bearing grease. You just want something that won't migrate - and that'll keep choke tubes from getting stuck.
