Thompson Center

I just installed a .204 Ruger barrel on my old style Thompson Center along with a new rifle stock and it will not fire off a round! No marks on the primer, either. Any ideas?

1) (This may be too simplistic) The T/C has a moveable firing pin which enables one frame to fire both rimfire and centerfire ammunition. Most likely, your frame is set on rimfire or is in between.
2) Either way, it sounds like a firing pin problem.

I feel foolish asking as I am sure you have, but did you look at the saftey on the hammer?

Thompson tells me it's a head space problem.
