There is also another potential problem on the T/C Contender. The older barrels have a 2 pc bolt and the newer ones have a 1 pc. GH
I just realized that I made a mistake on the bolts!
It is the
OLDER barrels that have the 1-pc bolt, and the
NEWER ones have the two piece.
At any rate, what your 'smith did, will likely fix the problem..
