Anyone with a little aptitude could build a FAL cheap, FrankenFALs with mixed parts were common items at gun shows.
Unless you can shoot it ~200 rounds to verify it runs, I would avoid it. Much better off getting a DSA or one from a known builder.
I have a few FALS. Imbels, Austrian, and a DSA.
Also have a Century receiver FrankenFAL L1A1 that runs perfectly fine.
All soft shooters, much easier than a G3. Not noted for accuracy like an AR10 but reliable rifles.
Good luck !
