Is this “Canadian safety course” a legitimate retail website?

I've been looking for some Monstrum optics (i know i know, I'm cheap) for my rf224. But barely see them on Canadian websites. This Canadian safety course has some listings, but I don't know if it is a trustworthy seller.

They are a drop shipper. I’ve ordered once from them for an item “in stock” and I waited 4 months to receive the item with no communication or responses.
I left a negative review due to the lack of communication and he called me on my phone the same day regarding the review. That just left a bad impression on me afterwards, that they would immediately respond to negative feedback but ignore questions regarding the status of the order.
