It's actually really bad. The clip is to small to kill anything other than a dreg. If your lucky in pvp 3-4 burst can kill but chances are you will empty the whole clip before someone dies cause of lag and by then your are already reloading the weapon instead of having it instantly reload. Also the range is awful and the recoil is awful. You can fix 1 or the other with perks, but not both at once.
