I may use the new to me BPS10. Plan on an RMR mounted. That means I have until Spring 2020 to get it back and practice with it. If not, I have an old single shot 10 that a PO installed a piece of 7/8" all thread in the buttstock over the stock bolt. A poor man's recoil reducer. Will shorten the LOP before hand. Be safe and Be Well, Rustyzipper.
