  Ulterior Observation, as an aggressive frame LMG doesn't really have a frame intrinsic outside of "high damage, high recoil". At base, by comparison with its peers, the stats are decent, benefitting from the boost at Tier 4/5 when barrel and magazine perks are enhanced - d2foundry.gg calculates that 47 Range translates to 29.55m hipfire or 47.28m when ADS before damage drop-off, 46 Stability is ×1.0650 flinch resistance, 45 Handling is 0.39s ready, 0.40s ADS and 0.36s stow speed, 32 Reload Speed is a glacial 5.24s reload and Magazine Size is 60 (max 87). You probably will need a bit of help with the barrel perk to control the recoil. With the magazine perk, maximise the size, use of the combat effect perks or maybe a little more help with the reload speed. For a pretty much all-purpose roll for add clearing, that can also be used for the occasional focusing down of harder enemies, the pairing of Subsistence in the first trait perk column to refill 10% of the magazine (20% when enhanced) from reserves, or Demolitionist to generate grenade energy to use to refill the magazine on a grenade use, either of which can work with Killing Tally for an up to ×1.3 damage boost for killing 3 enemies until you swap or reload or Binary Orbit's ×1.25 damage for 8.5s (10.5s when enhanced) for getting a light-based kill using weapons or abilities. The Exhaustive Research Origin Trait is very good for PvE - ADS for 1s at an enemy up to 60m away, and the next shot will fire a mini-rocket - these are affected by and can proc rocket-based perks and traits too - with a 5s cooldown. Recommended MW: Stability or Handling, with your preferred choice of mod/enhanced mod to boost weapon stats, ammo regeneration, or elemental pickups for builds - and don't forget to check any available seasonal fragile mods.

With the magazine perk, maximise the size, use of the combat effect perks or maybe a little more help with the reload speed. For Stasis builds, maybe with a double special loadout so this is your primary add-clearing weapon, the combination of Headstone to generate Stasis Crystals on crit kills with Rimestealer to generate Frost Armor stacks for destroying a crystal or frozen target (2 stacks when enhanced) is a tried and tested pairing.
