    I was wondering if a registered full auto trigger group (or post '86 sample) would work in a Federal Arms aluminum receiver? When considering a certain FA-91, I was told that that particular rifle had been taken out of full auto. Would that require substantial modifications, was the guy mistaken, what's the story on interchangeability here?

    It all depends on the trigger ledge specs. If they're HK then all is well. You will need a full-auto carrier though, or weld the notch on the bottom.

    AFAIK, all they do is modify a f/a trigger frame to fit the semi receiver. Really no idea how the U.S. sear market ever even developed. You'ld think that if the sears weren't available then nothing else would be, like the trip lever. :confused:
