I couldn't get your link to work. I have made a few out of walnut and also a black plastic called delrin. It is super stable at varying temperatures, easy to machine, and looks good. Bull barrel forarms are pretty easy if you have a small mill to cut the action end with. Tapered barrels are a pain in the butt. Especially the Encores, they have a double taper that is a real pain to match. If its a straight barrel I have got it down to about 3 hours to make one. I would post a pic but I don't have a digital camera or a scaner. I make mine with a wide bottom that narrows as it goes up, and also angled toward the front so that you can adjust your elavation by moving the gun forward or back. Pretty basic really, but it works and looks really good. KN
