ArmdLbrl, what the hell are you talking about? Metric FALs came before the L1a1, maybe not in SA, but elsewhere. They didn't remove the selector switches, they just installed one that won't let you rotate the selector into the FA notch, all L1a1s I've encountered have this as a standard feature. It was common knowledge before whatever happened in Rhodesia that 7.62mm rifles were basically a waste of ammo running on FA--M14s, FALs, whatever. All Commonwealth pattern FALs have a change lever that prevents you from switching to FA except for the L2a1 squad automatics.
How can a FAL not have a change lever? You seem to imply that they were somehow removed. I've seen SA R1s and they have a selector just like all other FALs. The selector is also the safety, and a critical component of the fire control parts, it would be very stupid to "remove it." It is pretty trivial to make a metric FAL work the same way. Also, you can do a simple mod to make inch mags fit metric rifles, or the metric mags work in inch guns without any mods at all.
Typical of a gun rag, the article is poorly researched and doesn't make a lot of sense. I'm sure if you are determined to defend your homeland, even bolt action rifles would work. Full-auto weapons, for suppression especially, are always preferred. If anything though, the AK toters were "out-gunned" (and probably fired theirs on semi most of the time also).
This article seems kind of dated, anyways--what legislation? All in all, a very weak argument for stopping a semi-auto ban!
