Forum:White Sniper Rifle

Ok guys, here's the deal. I ran into a Sniper Rifle of Purple rarity. It was a GGN50 White Sniper Rifle(exact title of the weapon), manufacturer was Atlas, and of course the entire weapon was white. The stats are kind of hard to remember but i think they were:

Damage: 937

Accuracy: 97.5

Fire Rate: 0.9

Magazine size: 6

With your standard plus xx% to various other stats. I held on to it for a while but I found myself lacking backpack space for other weapons and wish I had taken a screenshot of it but I have already sold it thinking it was no biggy. Now my question, is this weapon pretty rare? I have searched all over the internet to see if anyone had ran into one and found nothing on it. I would appreciate any feedback.
