Still prohib. DSA in the US bought all the Austrian machinery and produces brand new semi-only hard to convert with no auto sear slot receivers. Un-exportable, and would be declared a "variant" if they were somehow to get here.
The thing to remember is that all prohibs were listed by name when the OICs came out. Some had "and any variant..." added to their description. So for example, under FN FAL it lists all the FN model numbers, L1A1 and any comercial model (Springfield Armoury had a couple), and "any variant".
The reason we can buy Swiss Arms, CZ-858, M14s/M305 is because they were not being manufactured or imported when the OICs were issued, so they do not appear on "the list".
Anything that is on the list is verboten, and any "new" production of the same design is still prohib. For example, there is now a US produced semi auto version of the Styer AUG, and the H&K-91 (different names, new machinery etc), but they would still be "variants". In fact there is a .22 rimfire MP-5 look-alike that is currently working its way through the courts, prohib as a ""variant" despite being a blowback .22 rimfire. There is also a .22 AK looking rimfire rifle that is prohib as a "variant" of the AK.
