I made rank 5 and immediately bought the GD...spent about 15 motes to get this roll, which has two of the three perks I was looking for on this weapon. Rolled auto fire for first perk. Second perk tree has quickdraw, lightweight and braced frame. Last perk is firefly. Mainly going to use in PvE. UPDATE: rerolled it to get rodeo to address low stability and oiled frame to address the slow reload and firefly. Can run explosive rounds or high caliber rounds in lieu of oiled frame if needed.
