I'm currently trying to complete this gun and it awful. Some games are good but most games I'm horrible with it. I've tried Reflex sites, Fast mag, and the target finder for this gun. I found that Target finder works best and I may try select fire with it next time I'm on. What are some good class set ups for this gun ? You can include perks and primary gunfighter since I have most unlocked. Thanks in advance for the tips.
