The FA Cetmes are probably about the same boat as a current production CAI Cetme.
FA clones have those Gawd awful receivers though and they are aluminum, so they have their own set of problems. Some guys say the pin holes for the trunnion get wallowed out and make the trunnion/barrel assembly come loose.
Also, you can't use a collapsible stock with the FA receiver, but that might not effect you if you didnt want one to begin with.
So.... its a bit of a toss-up. You may or may not ahve any bugs to work out of the FA rifle... Id get the Century gun working if you had to choose between 1 or the other, but if you got the funds to have both..... by all means!
