I discovered this Unlimited Piron PBR-10 today on the steaming corpse of a Riptor. So at the moment it is the only one of its kind. I've done decay tests and entered the details in Entropedia. See the link above. It has a higher fire rate than the L PBRs at 59 per minute and the range is also better at 66 metres. Also the tier rates on this one are quite nice. See the images below for that. Current TT is approx 66ped. (Max 100ped). Unfortunately the dps doesn't really suit my hunting needs so I am looking to sell. I am happy to receive offers here in this thread or by PM. Also if you want to share your opinion on the value, I am fine with that happening in this thread. Normally that would get stopped by forum moderators but I am explicitly giving my consent.
