The FN-FALs and such were all surplus.
Um...that's utterly WRONG. Back in the early 80's many FAL's and SLR's were being sold brand new. Some were brand new manufacture from Australia, some were brand new right from FN Belgium.
Lever Arms used to be right downtown Vancouver Granville and Robson, right between Future Shop and the Sears. Back then, I saw they had brand new FN FAL's from Belgium, of every variant, including the short side-folder "Para" and "Congo" variants. They also had a heavy/long barreled version, similar to the C2, but semi. At that time, Expo86 was on I think, the AR-15 was still non-restricted, but the FN FAL/SLR were already Restricted for some time, and the guy in the shop explained the difference as being "range only".
In the 90's there was many surplus Indian, Israeli and British SLR/FAL's being sold cheap...but they were FAR from the first ones in the country in civilian hands.
