If you observe the Icebreaker Exotic Sniper Rifle, the Barrel upgrades will mostly say "More Range and Impact, Increased Recoil" or something similar. However, on the stat bars, there doesn't seem to be any change in the weapon, at least visually through the UI. Are these improvements perhaps more META, such as you'll notice the difference between recoils depending on which barrel you utilize? Hotfix on the item would be nice to at least see the visual differences when selecting a barrel for this weapon :)
