I have a bias towards YHM stuff, I really like the looks and quality. I own a both versions of the Phantom, and a set of sling mounts, I'm impressed with all of the parts I have, next will be some Yankee Hill Machine flip up sights for my flat-top AR.
It sucks that we here in Canada are limited in what flash suppressors we can buy, we just don't have the availability that the US has.
