Where to find parts?! First ar15/modern sporter build

I’m also looking for a fortis night rail from Canadian source, a 14" or 15 but they are nowhere to be fund!

CTCS has the 16"

Thanks this will help a ton. Makes it simple for me! Rifle is mainly going to be used for varmint hunting. Just trying to use quality parts. Buy once cry once right?
