Thompson Chamber

Hi Folks!
How can I pull the chamber from the Barrel if it sticks?
I've unscrew the Chamber with the Screw behind the Handguard,
but the Chamber won't come out......
Anyone an Idea??

I take it your barrel is the blocked one and not the open? if blocked its not easy the only solution i ever came up with was needle nosed pliers into the chamber and as gently put firmly as possible get hold of the det pin and start jiggling and pulling, probably not the answer you were looking for but you are pretty limited in what you can do with chamber.

Unfortunately it's the Blocked-Barrel-Version...
OK, I'll try your Way and hope in worst case I can get a new Chamber
at PFCGUK ...
Thanks for helping

A new chamber should not be a problem but you should not need one unless you completely destroy the det pin trying to get it out. Before MGC went out of business they changed the shape of the chamber it used to be the same diameter along its length but it changed and the chamber was narrowed at the end where the det pin connects so there was as step in the chamber, i have always wondered why they did this but maybe its stops the problem of the chamber sticking. Sorry i have no other ideas for you to pull the chamber out.

Hi
Common problem,
Try using a sharp point through the hole for the screw that holds chamber in, tap it gently, if you are precise, you can angle the point to slowly move it out of the barrel.
One thing that can happen is there is a small point of contact between the extractor and the barrel/chamber edge, this can become "burred" over and stop the chamber coming out smoothly, if this is the case remove the burr with dremmel or such like.

On the positive side the point through the hole always works for me:)

After some Hours of digging I've became the Chamber out of the Housing...
I have pull it wtih a long pointed forceps gripping at the Detonator-Pin- and Its all
remained intact... I'm a lucky one...
Now I have to work the Chamber that it fits...

Thank you all for helping!!
