I was going to just buy a new breech plug since we messed up one that got stuck. Looked at the cost of new plug, new nipple and new hex multi tool (my old one was a slot type)and the cost was just a few $ more to do the 209 conversion kit swap. Mine is a MK85 so I had to order a straight capper that cost me about $8 more I was not expecting. The LK like the MK may take this type capper and if you order direct from Knight they will exchange the one in the kit with the right one if you tell them. Sitting here now waiting on UPS man to deliver it....says out for delivery on their site.
