Canada adopted the m86/87 as the c3a1 to replace the 1200tx/m82/c3 in about 1988...well after the adoption of the AI L96
Of course some of that was because they cheated by "upgrading" the c3 by replacing merely the action and the scope.
Part of the "upgrade" was to reuse the originam c3 bolt, barrel and stock...unless they were worn out of course.
Why they wouldn't have "upgraded" to the m85 action i'm not sure...
