I have a JC Higgins Mod 44DL Leveraction .22. I know that the rifle is a store brand, and I also know that it's the same rifle as the Marlin Mod. 57. I need a firing pin and spring for this rifle. I've checked Numrichs, they, as of today, are out of stock, and a few others sites I can't seem to find what I need. Any help will be appreciated.
