I just used my key, since I'm Level 50 with my Maya now, and dear lord.

The Sniper Rifle I got is glorious. Over 22K damage, 3K electric damage per second, Burst fire while Zoomed, and increased Stability.

However it does take two bullets a shot, and it only holds 8 (9 with my boosted capacity.), so I only get to fire one full burst, then a single shot and reload.

Though when I near one shot a level 48 War Loader, I think I'm fine with this.

The other Item in the chest was an SMG with no special abilites, but does 4985 damage a bullet with a huge clip.
