Smoothbore barrel for GPR?

[aflineman]

Does anyone make a smoothbore barrel for the Lyman GPR righthand flintlock? I would like to get one to play with, if available.
Thank You

Is the GPR a 1 inch channel or 15/16ths?

15/16ths

I have one made by GM. Been told they have since discontinued them, but there have been comments made here that they would make another batch if they had enough pre-ordered. If that fails, may have to just get a 15/16ths and build it up to work--or try to find a used one.

I picked one up recently from Track of the Wolf. It is a GM barrel, .54 cal; TotW does the modifications needed to have it fit the GPR. I still needed to do a bit of minor fitting to get it to drop in.
Shoots nicely.

Thanks. I just picked up a 1/60 twist barrel for it. After the "mad money" builds back up, I will get ahold of track of the Wolf and ask them about a smoothbore.
I also have a lead on a smoothbore trade rifle that a "friend of a friend" may have for cheap. Hopefully that pans out into something worthwhile.
