FIRST, DO NOT USE ANY STRIPPER INDOORS. some say that they are environmentaly friendly but are still for outdoor use. they all cause a chemical reaction with the finish and can be toxic.
I could be wrong but have never seen one that says it is safe for indoor use, if you finde one I would be very interested in how well it works
as for strippers, you have to read them good, some will lift the grain of the wood and ruin your stock, some will not take off oil based stains and some will not remove the clear hard top coats. I use an aircraft stripper from LOWES that works good and does not lift the grain of the wood. you will need a stiff brush to clean out the checkering and I use a plastic "bondo applicator" to scrape off the finish, it is plastic and will contour to the shape of the stock. the finish remover can melt the scrapper so you will need a few of them to do a stock. or use a steel scrapper but try not to gouge the wood. The forend is a real joy to get it completely stripped.
you can put a LOT of hours into refinishing a stock and forend properly.
