coming from someone (ps4) who had made unbroken only sniping, mainly with supremacy, my personal god roll would be -corcscrew rifling (number 1) or fluted barrel (number 2 ) for the first slot. -next slot, armor piercing (collaterals baby!) and small range boost, tied with light mag for the same range boost, but faster reloads as well. this is followed by ricochet rounds ( range and stablity) then high cal for the small range boost. im not sure but i think i have seen this gun roll with accurized rounds in this slot, and if it does, this would be my top tier choice as the base range on supremacy is low, tends to fall off in accuracy/reticle stickiness in longer sight lines (think vostok tram side, solitude from A flag spawn to the far left railings flank, equinox in general, etc) //should be noted all the range boosts above are the same (+5 range and range = accuracy and aim assist) this catagory is a preference thing but theres many fine choices. try to up ur range in the first two barrel and magazine options as much as you can. - SNAPSHOT is 100x better than any of the others. it begins to have God roll potential with snapshot alone (due to high base handling in the gun). the others simply arent worth mentioning. -next perk tree would go to rampage by a HUGE margin, followed my rapid hit. kill clip next (but not so great) then triple tap for last place imho. -masterwork HANDLING is the clear choice , but range isnt THAT far off. handling is what makes the gun even snappier when zooming in, and allows u to quickly switch into the weapon (quickdraw). finally, put a RADAR mod inside this weapon. base aim assistence is top tier (77 AA) and if ur able to get some range boosts in the first couple perk trees, targetting adjuster is simply not necessary as these will boost the AA. a helmet with the +10 boost to all precision weapons (hand cannons AND snipers) is a good match to this weapon. you can check my sniper stats for credibility : https://destinytracker.com/d2/profile/psn/m00se0032/detailed (90% accuracy with around 5800 kills) sorry for the text wall, but this has been one of my favorite guns in PVP since D1 (pooped on her benevolence imo) sadly however, i have one of the worst rolls (ambitous assassin and triple tap damn RNG!!!) but the masterwork is for handling with boosts to range and handling so it slaughters anyway. currently around 5000 confirmed kills so far on it. about to run the raid again to try and get my god roll or close to it as there is nothing else to go for at this point for me 😂 GL and HF out there guardian!!
