Replacement ramrods for the KRB and the KP1 now available from Cain's Outdoor - you'll need to call Ed Cain as these are not listed on the website.
I think he said 29.95 each. These rods are cut to length for those rifles, have 3/8" jag end and 23/64" opposite end. KRB's is 26" long.
One heckuva an improvement over the factory arrow shafts. Made from Delrin, brass, and steel.
