Works on any variant really, I run this on my A because its already mastered. You can swap the lasers out to your preference without really affecting the firepower and DPS to much ERSML or whatever. For me it plays like the old 6SPL assassin back when a spl did 6 damage but this thing does the job way more efficiently. Just go for those rear CT's and never stop moving and you'll put the fear of the assassin cheetah back into this game. As always would love to see your changes and ideas or criticism bellow.
