back some 7 or so years ago I bought a PIONEER ARMS PPS-43 pistol when the market was flat, flat, flat.....and ROYAL TIGER were blowing them out for 200 some bucks, which was cheaper and far less of a headache then building one from a parts kit.
the only thing I bought a parts kit was for the spring and stock release button when I SBR'd it........it cost me like 70 bucks, but hey I got 2 mags with that kit .
