I re-forged mine and stopped at Rangefinder, Flared Magwell and Luck in the Chamber. Extra range, quicker re-load (better when running Gunslinger Hunter) and a round doing extra damage. Better than the standard perks. Would have preferred something over Luck in the Chamber. Exploding rounds were good but not great and its impact is good, hits very hard. Not the best but a solid hand cannon. Re-forged Perun's Fire last IB and got Accelerated Coils. The re-charge is insanely quick for a fusion rifle, almost Plan C quick....Now its totally leveled up it is INSANE in PvE and PvP...
