I actually don't know...I love it because it'll get you out of tough situations in the game. You'll never be backed into a corner in PvE, and it almost always promises a kill in PvP but...it's so hard to use that it might just be better to go with something else. Upgrade - range and accuracy: Good luck with the 20 second reload and 3 round clip. Upgrade - clip to 5: Maybe if you hold your controller between your legs, it'll steady the thing (My preferred because most missed shots come back to your mag) Upgrade - reload speed: Congrats on your new Murmur.
