My neighbor just put one together from a kit from sportsmanship guide. It was on sale, no lower and no barrel. He found a new barrel and used an Anderson lower. The parts were a little rough on finish but it shoots great. If the ones AK builder has look that good, I would go that rout. Barrel already there. Then get the old style lower from nodak and there ya go. The kits should have mostly all orig colt parts.
