I'm new to the forums so all this stuff is still a bit confusing. I'm wanting to buy this gun then save up my money for a sear pack to convert it (I have the means to do so). From what I've gathered, milling off the block is a legal grey area and a letter from the ATF would help to calm the nerves of those capable of doing it, so it could be a while until we know for sure. Insofar as that, would it at all be possible to convert a semi-auto BOLT CARRIER to a full auto one by welding back on the material then milling it to spec? I know this is a very, very stupid question but I'm kinda high-strung when it comes to my guns and don't like them to be mismatching/unoriginal.
Planning on getting a 4 position sear pack btw so if there is any issues with that as well please let me know.
