Every now and then you will see a VFC HK416 for sale in the classifieds once you get age verified but it will almost always be a used weapon if you even find one. They have been out of production for 2-3 years now and you will not be able to get new ones. They are also more expensive because of rarity. I only seen 2 of them on sale for all of last year. Very few of them entered the Canadian market.
There are other makers of the 416 however. The Dboys 416 is a lower quality clone but decent enough version of the VFC 416.
Jing Gong and SRC also make clones of the 416 (but they are not based on the VFC version).
