I have a Scorpion pistol. If i wanted to SBR it, I am supposed to change out some components to make it 922r compliant. So if you buy all the components (either piece part or kit) and install them. how does this prove you are in compliance. do all the old parts and new parts have P/N and S/N on them to to link prove it.
I assume the Franklin Armory binary trigger gets you four foreign parts off the list, right? https://franklinarmory.com/franklin-armory-bfsiii-cz-c1/
So on my Scorpion, i have replaced the trigger spring and the safety switch. If you order online, how do you know anything is made in America. To me, i don't see how they can enforce this law because it is impossible to verify.
