Back in the early/mid 80's the Mini-14 was a great entry level rifle into the .223 world until you saved up a little money for an HK93/Galil AR/Steyr AUG/etc.
As a result there were a LOT of accessories available for the Mini-14, and if a 18.5" semi-auto .223 rifle was cool to shoot.....a 18.5" semi-auto .223 with a folding stock was even cooler! That led to a few different aftermarket companies producing folding stocks for the Mini-14 because the Factory Folding Mini-14 was the same price as an AR-15 and the GB model with the Factory Folding stock AND bayonet lug was almost impossible to find as they were sold as soon as the dealer (if they could even get them) put them on the wall.
Fast forward 30 years; the firearms world in Canada has changed dramatically and the Mini-14 has been eclipsed by the AR-15 for various reasons, but if you can find one in the $1200-$1500 range, an original Factory Folder Mini-14 is still a great rifle.
