You are right Tom, there is still yet another small part. C2 change levers are not the only answer, and we are not talking safety sears ;D.
However, back in 1983 when the FN FAL and variants went restricted, it was a preventitive measure, as at that time there were thousands of Aussie L1A1s being imported thru Lever Arms (Van BC) and other sources, even offering 'investor packs' of 4 rifles w/EIS. The Cdn govt did not wnat its general law abiding gun owning populus to openly have such rifles without restriction.
Then later in the 90's they went prohibited. The key to selective fire capability is a safety sear in the upper reciever. In the USA, this milled spot on the reciever has been deleted in the manufacturing process (a BATF thing), so the rifle can never fire other than semi auto. However in Canada, a FN FAL and variant is just that, regardless of milled slots for safety sears or not, and all are now prohibited.
Many Cdn imported rifles were sold w/sears, and some later were sold without sears and a small area ground away on the b/blk carrier where it engages the s/sear. This did nothing, but disfigure the rifle part (although rendereing a quick fix for conversion). An argument for the sear was brought forward, as it enabled the rifle not to fire when out of bty, where as one without a sear could possibly do so. There was never any law related to such removal of parts, as far as Saskatchewan anyways.
When I lived in Canada, I at one time had 1 8L C1A1, 2 Indian minty 1A1s, 1 Aussie L1A1, 1 Brit L1A1 and 1 Aussie L2A1. All had s/sears and were in their original configuartion, with the exception of the L2, which had basic semi-auto parts and change lever. I never had a problem, even with the countless re-registering becuase of an incompetant system.
Our own honwesty provided a ruse for the sneaky Liberal federal government to confiscate and further restrict firearms in Canada, and the criminals using stolen, or illegally imported guns don't care about honesty, do they.
Its only going to get worse, andI hate to asy I told ya so. One day soon, the only guns in Canada will be owned by police, Defence Force and criminals, and thats fast approaching, and will come sooner than later.
Cheers,
