The above pretty much nailed it. I have had good luck with hardware store strippers even with a Browning that had about 1/4 inch of that glossy crap they used to use. Apply and let sit, brush or wipe off, use a tooth brush in tight spots and checkering. If you search Midway or any of the other suppliers they will have kits and probably DVD's. It is not hard, in fact it is rather fun and you will be proud of the results every time you use the rifle.
