Well, if you're ever truly desperate for energy, leveling the weapon before dismantling gives more mats. (you don't have to actually buy the upgrades) So something to keep in mind when turning in bounties, I guess.
But yeah I freaking love my VoC. Headshot machine all day. Aim once, hold down button. I use the extra ammo perk - the max stability one seems awesome, but it's actually totally overkill.
Now if only I could get some goddamn armor.
