AR parts

[lone-wolf]

But seriously where do you guys like shopping?

Brownells, unfortunately for our local dealers.
I don't really think there's one stop shopping in Canada(there is, but not so much if mix and matching brands), probably going to need multiple orders.
One shot tactical and canadian tactical cowboy supplies for rainier arms barrels, Arms East has a lot of the parts kits iirc
Maybe SFRC for the stripped upper and lower
