Yup, that about sums it up.
When they first restricted the FN rifle(which as I recall came about before C17 or C68), they had a technical drawing that was distributed showing a weld they wanted done to neuter it...I think it was to weld up the hole that the safety(?) sear came up through. Then someone figured out that that made the gun unsafe...the FN was after all designed to use that third sear as part of it's normal semi auto firing sequence, plus the heat of the welding could bugger up the careful heat treatment the receiver received when manufactured.
Since it was fairly (actually extremely) easy to make it fire full auto, as they knew very well, they wanted to avoid a situation such as was seen with Lee Enfield rifles, where there were thousands of them being dumped at very low prices. I read that a number of countries were getting ready to sell off their FN's and the last thing they wanted to see was them being sold for $50 at hardware stores etc.
I'm not their mother, but in some way looking at it from their point of view, I can understand that concern. They'd been watching their soldiers breaking the rules with these rifles for a couple of decades and knew that in civilian hands there'd be no controlling the things...I never got to do it but you don't have to talk to too many militia/soldier types to get the stories flowing about the groundhog that ran across the range and they blasted it with their C1's on full auto with a stick wedged into the sears...
I also read one on here a couple of months ago, some soldiers were on a training mission and one jimmied the sears to fire full auto, then the gun jammed open and he couldn't remove the evidence...luckily for him they didn't know who had been using it, he could have gotten in a lot of trouble.
As for those $129-$179 Ishapore FN's...I bought one, had it for a while and I'm not sure it was even worth that much. The Lithgow L1A1 and the Canadian C1's were the real gems IMHO.
