I have my parts kit, but much more goes into this receiver choice than I anticipated, as in purchasing a receiver flats and contact some one knowledgeable on bending and Tig welding or buy a welded up receiver then contact some one to complete the internals inside...I'm lost...Oh I already know it's cheaper to buy a new PTR or Cetme. I have that, I want an Ol school clone....any help is much appreciated.. thanks in advance..
