Reply #54: Finding the specifics can be daunting, but generally enough changes have been made so it is not easy

"The hammer can be slightly different, as hammers made specifically for semi-autos don't have the notch for the auto sear. The sear/disconnector is slightly different in a semi auto as well, some material has been removed. There are also several other parts that have been ground down to keep someone from just dropping in the FA parts, as well as certain pieces that are built differently so as not to accept FA parts. It's not just a couple things, it's quite a few."

Guns like Thompsons and ARs have different receivers then full auto originals, plus a bunch of other parts. Keeps one from just 'dropping in' FA parts.


I am not too familiar with specifics, others here know way more.
