I know you were not suggesting we rip off the folks at Wolverine. I am still a little chapped that another well known dealer did exactly that to us not that long ago.
I suspect if I approached John or Matt we could work something out, but it still will take an investment that I simply don't have at this time.
We can always do assembly and frankly on custom barrels we prefer to do the assembly. That way if the gas port requires being opened up to ensure cycling we can deal with that rather than using an arbitrary size and hoping for the best. This solves under or over gassing issues.
