They're probably talking about the Beta mags. There was rumor that they were going to fit the .308 mag to the CETME and FAL about a year ago and they did come out with a .308 beta mag.... but it is listed as for the
M1A/M14. Now, there's always the possibility that they finally do come out with one, but I'm just not going to hold my breath, as much as I'd like for it to happen.
Do you have any more explicit info on what the Shotgun News article said in regards to the magazine?
