So I was doing the quest for the first curse and I was on the part with Imprecation I completed all the requirements for the gun and I went to the tower to turn it In when I did I noticed I had no primary weapon in my primary slot, but I swapped the weapons around on my back to find I had an auto rifle as my primary I went into the crucible to find if it was functional and what do you know it is a BEAST! The only auto rifle iflve found that can compete with pulse rifles. Then I invited a friend to tell the odd news to and we went into a rumble game to discover the name of the mystery weapon and it was a surprise the Marshal a-0 I looked it up on the armory and guess what it doesn't exist so the mystery continues if you know what this gun is please let me know bungie if you read this please make it a gun that is permanent in my inventory even if it's just a common I think it's really cool and id like to keep it.
