I have this one breech plug that I have acquired along the way, I know its from knight and I believe its 209 for a long range hunter or a disc ? Which bolt would it work with ? Which adapter would the bolt use ? I had a bolt with my long rang hunter that had a metal adapter that would lock into the bolt to hold I believe a 209 primer. Any help would be greatly appreciated.... if its something I can identify and someone has a need I will put it up for sale.
