A bounty will help me level up Atheon's Epilogue? I'm just asking. If I'm doing it wrong I'd like to know. I am under the impression that to unlock weapon upgrades for my equipped AR I need to shoot things with it, right? The higher the level and more of them would seem like the best way to do that.

It will take ages to upgrade your gear and weapons by killing stuff.when you turn in bounties the xp goes straight to whatever your leveling

You are wrong. Equipped items gain xp. Watch them after you turn in your next set of bounties.

Oh, okay thanks:) That's why I asked.
