Very nice write up. I've built 3 mausers on the tailgate of the truck using all homemade tools like you. Except the reamers of course. Two of mine are in stock blanks I bought but one is in a cut down military stock. I couldn't decide on a caliber so just screwed the 8mm barrel back on and cut it to 25". I have a Williams peep and a fiber optic front. I call it my rainy day gun. Woody
