I kknow they got purchased by Smith and Wesson. I think fox ridge might be where he was getting the barrels. They are producing barrel now from eabco and not getting them from the T/C factory now. Other than that I can think of nothing.
EABCO = T/C Contender Custom Shop Barrels - Made to Order by EABCO
MGM = Match grade Machine Custom Thompson Center Encore, Contender, G2 barrels, and Pro Hunter - MGM
T/c = Thompson/Center - America's Master Gunmaker
