My first “Alliance Rifleman” transmog was based on the vanilla hunter PvP gear. The problem with that one is unless you’re high ranked (or earned rank 9+ in vanilla), it’s unavailable to you. This new one, however, is available to anyone who builds a Dwarven Bunker in their garrison. Even though it looks like plate, it can be worn by any armor class. It just so happens that it looks pretty badass on a dwarf. Sorry, Hordies, this one is Alliance only (except the gun and goggles).

I’ve put this set together in a Wowhead item comparison so you can quickly view it on other races in 3D (click the little triangle above the item icons).
