Did the LB rifle you saw in service still have the Canadian disc sight?
I've heard it said that one of the big arms vendors in Canadais sitting on over a thousand C1A1s that it can't sell. Supposedly they're ex Ontario Provincial Police rifles that were initially sold to a British dealer, then when the laws changed the lot was purchased by the Canadian vendor, who brought them back to Canada...just in time for THEIR laws to change too!
