Challenge you to solo it with lower GearScore then 199 :)
Edit : To explain few things people have been asking:
1. Crit damage on magazine is there because I run pulse and it gives me better accuracy, longer lasting clip and actually more dps while pulse is active. I use weapon damage for PvP over Rate of fire for similar reasons. I want to keep good accuracy on the weapon. Rate of fire ruins that.
2. If you are soloing so obviously you are the only person that can pulse then in that situation skill power gives you more damage then firearms through pulse bonuses. Added benefit is better heal as well. People that spec only firearms need someone with decent skill power to pulse for them to get the benefit from it.
3. What is giving me this high damage is bonus damage on weapons after using skills, pulse, elite damage and enemy armor damage bonuses the gear has.
4. You can get 7 medkits by using the paramedic backpack when you restock. It's a feature of the game that Massive employees use on stream.
