For Sale is a 36 inch, 13/16 across the flats Green Mountain black powder barrel in .36 Caliber. I haven't found these in production for a long time. I think it is 1-48 twist. The breech was tapped at the factory 9/16-18. New and unused it has been sitting for nearly 20 years for a project that never happened.

$195.00 / Shipped CONUS. Payment by USPS Money Order or PayPal
