I have a customer's .22 Ruger Mark I pistol that needs a barrel. A decent used barrel will work. It currently has the 6 7/8 inch target barrel on it, but beggars can't be choosers. This guy is tighter than Dick's hatband, so he isn't interested in "any fancy new barrel" (his words).

Bill, have you tried posting over on rimfire central? You may have a larger audience there.
