Looks like it would be cheaper just to buy a ready built SA.I see they go for $6-700.
With the parts kit,semi bolt,receiver,and compliance parts;doesnt look like you are going to save much.
Tell me I'm wrong!-I'd love to have one of those guns too! Just bought a CZ-52 on Gunbroker for $135.,and it has new rollers,new steel firing pin,Wolf spring,and a Hogue slip on grip rubber(?)-HOT little round!!!!!!
