Nice job. Your 21 inch ‘03 looks more like a carbine than mine does. Mine’s a throwback to the short rifle concept. I like your build. Also agree that the ‘03 milled furniture is sharper looking than the 03a3 stuff. Try the Birchwood Casey rusty walnut military stain. It’s water based and doesn’t look like much until you put on multiple coats. The first ‘03 stock I did was sanded bare but the second one I didn’t sand just wooled and it had some kind of stain on it but both turned out pretty good. Don’t get lost without your compass.
