Advice on purchase

Friend of a friend has a 3yr old seekins havoc bravo with MK6 3-18 he needs to sale. 80rds down a fresh factory rebarrel.
He is asking $2500 is that a reasonable price?
He needs to sell it?

Mk6 scopes typically sell for $1500-$2000 in the PX, depending on condition and reticle. Unless it's an ECOS DAGR version - those have QR codes and other markings on the top of the objective's bell and typically sell for north of $3k.
 
The general theme I have heard from most people who owned the mk6 was disappointment. I have heard from many that the mk5 was better.
Agree with respect to the standard Mk6, sold mine a while back..The ECOS contract scopes seem to be made a little differently/better. The glass is def brighter/crisper to my eyes.

I have an ECOS version and used to also own a standard ver w/the TMR reticle. Had them out one day side by side and the ECOS glass was noticeably better from my POV. I still have the ECOS version.
