Well, here is how they are getting around the latest rules revision.
Century is importing low capacity barreled AK actions. They then convert the receiver to accept 30rd magazines. They put on the furniture, and enough US parts to make it legal and bam!! US mfg rifle imported from Romania.
I was at AIM yesterday and asked because I had heard rumors that CAI was doing this. Guy steps in back says "yep here is a smple gun they sent us" So cheap AK's will be around for a while unless they stop the US mfg of high capacity rifles. I believe that would take an act of congress not a rules interpretation by ATF.
I can't speak about FAL's. Those may eventually dry up. I know STG kits, decent ones are very scarce and expensive. All the Imbel stuff that is coming in now where probably on already approved form 6's before Aug.
