I do have a question, being a new member here. If I buy a parts kit from a company (Centerfire Systems), do they remove the so-called ?bad? parts and replace them with semi-auto or do they just not send them? As far as building an AK, I was looking at the AMD-63 parts kit and a pre-built receiver from Arsenal USA, Like the type 5 or the complete barreled receiver. Anyone out there know if this will work or if these receivers are any good? Ok I know it?s now like three questions. I?d like to build my own receiver but can?t and won?t even try to bend, drill, mill or whatever it takes. All I want is a legal (semi-auto) AK and don?t mind getting a friend with an FFL to receive a papered receiver for me. And yes I know I won?t save money this way, but I will learn from it like I did with my AR-15. A pre-thanks for any answers I receive.
