Advanced Rifling is an Attachment.
Effect[]
Increases range of any weapon by 20%. It is best used on shotguns and Elementals, because their range is very short. 20% is not much, but it can help to kill enemies trying to run away from you. DB12 shotgun and MTS 255 shotgun is especially powerful with this mod, since DB12 has high damage, but very short range. MTS 255 has even less range, but the damage is the highest of the normal shotgun class.
It is also effective on close or mid range Experimentals: Ion Cannon and Laser Cutter (close range only) and Pulse Rifle (medium range).
