RE: GM Barrel Threads

If you are talking about the flash hole on the flinter, its the same as the T/C. Not sure the thread size.

RE: GM Barrel Threads

I believe they are talking about the bolster clean out screw. I would just give Kerry a call at Green Mountain and ask her. If you lost the one you got, they might be able to replace it.

RE: GM Barrel Threads

I'm talking about the hole on top of the barrel by the tang. It looks like you could mount a weaver style rail using it and the screw hole(s) from the rear sight. It is a flintlock barrel but it isn't the vent, it's on top and to the rear.
