I’ve used Citri-Strip Klein-Strip and Safety-Strip for years as the least invasive/destructive means I know of. I’ve used sandblasting and oven cleaner (in my early days) but that is an extreme in my experience which means I wouldn’t recommend them for anything you prize. The aforementioned strippers are not going to be the fastest way forward and in some instances will require multiple cycles of coat-scrub-wipe-rinse (always scrub with a greenie pad and hot water to rinse, it pops some dents out!) which means time but it does not harm the wood. Pick your tolerance for time/damage and proceed. Best wishes with your project, I’ve a CZ 452 I’m very fond of, fine rifles.
