Can anyone give me any information on a PPSH-43 Parts Kit from Numrich? It says 99.95, then it says "All NFA Rules Apply." Does that mean it's full auto? It also says "ATF Approved" and "less barrel." I can find a barrel for a couple hundred...does that mean I can put one of these together for a couple hundred bucks? I've seen them in action and they're pretty cool looking...ok...DIFFERENT looking guns, which is right up my alley. Any recommendations from the INGO members?
