ok, i will reluctantly admit that i've had one of these parts kits for a couple of months, and have considered building it into a semi-auto. but i very much do NOT want to break the rules and run afoul of the atf. now i have two specific concerns, ease of re-conversion back to full auto, and now "SBR".
it would probably be just as easy to convert it back to full as to build the sten as a semi-auto in the first place. after all, if i can weld or cut or drill a tube or disconnecter, i can reverse the process too.
so just how much trouble do i have to go to in order to convince atf that i dont want to make a submachine gun? would spot welding the selector in "semi" satisfy them?
secondly, it does have a short barrel, about 8 or 9 inches. does this create a short barreled rifle problem?
i think it would be fun to show up at the range with a sten, even if it is "only" semi-auto. but am i better off to just leave the parts set in a bag and forget them?
