I refinished the stock on my BL-3 (1973 gun)last winter with no problems using a standard paint remover/stripper product purchased at the local hardware store. The stock had a thick polyurethane type finish on it. The paint remover product was a citrus (orange) scented product that required reasonable ventilation but nothing really drastic. It took about three coats to get it all off. The first coat took approximately 3/4 of it after a half hour wait. The next coat did almost all of the remainder and the final coat did the small bit that was left. Definitely use rubber/plastic gloves when using the paint remover/stripper. Use a brass "toothbrush" type brush in the checkering. After using the paint remover product I washed it down well and let it dry for a couple of days. Then a light sanding with fine sandpaper was all it took for a good refinish start. Apply the stain of your choice and then the finish of your choice. It took me a month or so of every other evening work of a half hour or so to produce a very nice finish on this stock.
