Question: Which mob drops Piron PBR-47 (L) ?

[Bolivar]

I was wondering if entropiawiki was accurate.
Can Piron PBR-47 (L) only be looted from Oweko Prowler, or are the other mobs (maybe on Calypso)?

PIRON are Ark weapons.

I am pretty sure I looted one of those in one of the dev spawn events on Arkadia. It is, as mentioned, an Arkadia weapon series and I am fairly certain they only drop on Arkadia.

If I remember correctly I got them from Riptors and Owekos. Maybe even Oratans.
