Pretty much one of the most obvious builds for the Sleipnir since it's hardpoints were revealed. Simple, yet effective build including minor shielding capacities with the arms. Annecdotical evidence of effectiveness: BTW, Bear Claw used the same build, only skipping the MLas for another ton of ammo.
Time for an upgrade. More speed, more ammo (thanks to the ST) and a higher sustained DPS. Not sure about that single ML.
