Weapons
Truck
Great general use sniper, and my main choice for mobbing.
- Torgue (Impact Mag) is nice for big damage. Also fun with an air-burst enhancement.
- Daedalus (Underbarrel/Multi-Loader) (Shotgun mode) is nasty.
- The Big Rocket underbarrel is pretty fun and can do some one-shots.
- A default, no licensed parts version can roll very high damage and is great.
Rooker
The main firing mode is decent for general use. The big deal here is the underbarrel: it can annihilate bosses by itself, and also act as passive damage during mobbing for with this weapon or any other you swap to after shooting out the needles.
Order Sniper
Piktun. Ultimate 'normal gun' for one-shots of any health bar. Also works well for mobbing, just charge it a bit for the stronger enemies.
- The highest damage we've seen is above 6k base, with a Torgue (Impact Mag) or Torgue (Sticky Mag) license.
- A Torgue (Sticky Mag) license is extremely powerful: the sticky can itself proc bleeds which can stack
Contamination for you. Once you have enough stacks, manually detonate for a chunky one-shot through guaranteed bleed. - A Shotgun Mode Daedalus (Underbarrel/Multi-Loader), alongside either Torgue (Impact Mag) or Torgue (Sticky Mag) is also very good. The sticky mode can apply six stacks of Contamination on the impact hit (three from base hit, three from
Blood Is Power), which will nearly guarantee all bleeds on detonation. - Jakobs (Ricochet Accessory) is also alright when paired with Torgue (Impact Mag), since the ricochet can hit the ground and hit the boss again. It has lower base damage though, and is a poor strategy against flying bosses.
Order ARTediore AR
Drone underbarrels of your choosing. Kill drone on Order AR, Support drone on Tediore AR.
- Kill drones can help give a breather during dense mobbing. Support drones work on you and Trouble.
Blood Shot + Amp gets snapshotted into the drones.
Other sniper weapon options
Other general weapon options
Any weapon you find comfortable as backup. I like Balor 
Jakobs Shotgun and 
Hot Slugger, but any good legendary is a respectable fallback. Honorable mention to 
Bod of course.
Underbarrels
- Rooker,
Oscar Mike 'Space Laser', Spread Launcher, Knife Launcher, Tasers, Beam-tossers, Kill Drones, Flintlocks, Energy Blast, Turbine Cleaver, Seeker Rockets... the list goes on. Any underbarrel with potent damage can be useful here, or even turned into a one-shot machine.
Repkit
Triple Bypass
With an Amp part. The best general use option.
Order Repkit or any other Purple
With an Amp part and Enrage. The perfect option for one-shots.
Bloodletter double dips Enrage's "30% All Damage".
Ordnance
Completely up to you. Utility against viles or just pure damage.
'Crit Knife' 
Jakobs Grenade
- 'Crit Knife' Jakobs Grenade is useful at reducing RNG reliance on boss one-shots. It's also a big boost to bleed.
Slippy is nice against vile enemies.
Firepot is a fun grenade for general use. A crit chance variant can stack Contamination somewhat well.
A Heavy Ordnance with high single-shot damage can be strong for a singular shot provided you Repkit right before swapping to it for Blood Shot access.
Class Mods
Main general use option, due to the blood shot retrigger on crits.
Ideal Skill rolls would be:
- +5 Blood Shot: +2
Guns and Needles
Ideal Stat rolls would be, in descending priority:
- Kinetic Damage > Skill Damage > Maximum Health Capacity
- Bleed double dips kinetic and skill damage. Maximum Health for Blood Shot will not help too much because of our already high starting base damage being multiplied by amp.
Great for general use and excellent for boss one-shots.
Ideal Skill rolls would be:
- +5 Bloodletter: +2
Leeching Attunement or +2 
Material Components
Ideal Stat rolls would be:
- Kinetic Damage or Skill Damage; Status Effect Chance; Skill Crit Chance.
- Bleed double dips kinetic and skill damage.
Another general use option, and solid option for boss one-shots.
Better amp uptime and shield options but requires manual triggers of Blood Shot to be best used.
Ideal Skill roll combinations could be:
- +4 or +5
Blood Is Magic; +3 or +2 
Corporeal (Bleed double dips both) - +3
Grave Thirst; +Any distribution between Blood Is Magic and Corporeal.
Ideal Stat rolls would be, in descending priority:
- Kinetic Damage > Skill Damage
- Bleed double dips kinetic and skill damage.
Shields
Guardian Angel
With 150% Amp, this is the ideal shield for this due to its fast recharge and short delay.
Watts 4 Dinner or Amp Shield
With 150% Amp, these are the second best-in-slot. With a 
Teen Witch, the Watts 4 Dinner becomes overall best.
Enhancements 
Jakobs EnhancementOrder EnhancementTorgue Enhancement
There's some options here:
Quintain; 
Multistrike; Purple Piercer Jakobs Enhancement
- All of these are really good for our jakobs or jakobs-licensed weapons. The crit chance acts as a nice fallback in case of missed headshots, or is simply even more crit chance.
Primadiem; 
Ouroboros; Purple Power Shot Order Enhancement
- Excellent for boss one-shots and general use of Order Sniper rifles.
Pumper; 
Big Banger; Purple Headringer Torgue Enhancement
- All good if using torgue-licensed parts. The tradeoff is some utility and possibly damage compared to the jakobs ones, depends on which.
- Pumper can help with the slower Torgue (Impact Mag) projectiles and helps kill enemies that are behind cover. However it does seem to occasionally result in missed headshots due to its special effect, but you can somewhat combat that by aiming above the head, kinda.
For stat rolls, look for:
- Gun Damage
- Sniper Rifle Damage
- Gun Crit Damage/Sniper Rifle Crit Damage
- Gun Status Effect Chance
Vex
Phase Phamiliar
Incarnate instead. It has the highest peak impact damage and is a reliable setup if one wants to perform Boss One-Shots using 
Prismatic Ichor or 
Prismatic Weaponry to achieve a very high ceiling of damage and consistent one shots.
Dead Ringer.
Finnity XXX-L. If you're looking for a build around or that works with that, I recommend Katchenz's or LDKSVB.
