That's one hell of a sharp lookin Rifle Bud!!
It's been a long time since Canada used the thermal mold magazines though (mid to late nineties if memory serves). Good god I was happy to see those things go, those things were forever shattering and bullets scattering all over the place.
Canada has since switched to the standard metal magazines, an example of which you can see
here.
Again nice rifle Bud!!
Cheers !!
