Guild Wars 2

I noticed a the weapon Tybalt carried was a sniper rifle of some sort. After doing some research, I found it resembled the Plated Sniper Rifle skin I previewed at the PvP storage.

My question is how can I obtain this amazing skin in PvE for my Warrior and Engineer?

I’ve heard about weapons called The Hunter and The Predator, but I have no clues how to obtain them, let alone what they even look like! (The Hunter is selling on Trade Post for 90 Gold)

Is the Plated Sniper Rifle actually one of the Legendary Rifle weapons? Or is it a PvP-exclusive item? How do I obtain it in PvE?

Wish I could find this skin as well in PvE as I would love to have it on my Warrior or Engineer as well.
