Get yourself a 1/4" x 36" hardwood dowel from the hardware store. Cut a slot about 3/4" deep in one end with a hacksaw blade, and round it off. Use a small patch in the slot to clean the patent breech - push it in and pull it out with a twisting motion. No - it won't come off. I use this one for my Renegade's GM barrels and my Great Plains flintlock.
