Century actually started using Nodak spuds. To me they are the best stamped receiver on the market. The only receiver I will build on. The downside is the monkeys at century have been using us barrels. They have very poor eyesight and tooling to do the job of building an ak. Thier rivets look like crap, alot of thier guns are improperly headspaced and fsb's and gasblocks and rsbs are canted,handguard retainers are notched way to loose.Pretty much every simple task for a seasoned builder they seem to screwup. I cant figure out how anyone who is allowed to build guns for a living could improperly headspace an ak.
