Just so everyone knows, these non-public ZCO failures on big magnum that I hear about are not from
@wooferocau. I tagged him because he had some ZCO issues that I can’t remember if he’s ever explicitly detailed. I don’t know exactly what they were, or I’ve forgotten lol. He’s just one of the few who’s put his name on a report. He’s had lots of issues with certain S&B models too, but other S&B’s seem to work fine.
But let’s set aside Mr. Woof…I probably shouldn’t have even brought up his name as some try to discredit ALL ZCO problem reports by alluding to his history on the matter.
Anyway, like
@kthomas has heard, there are a few people quietly talking. But the fallout has been apparently and largely mitigated due to:
- ZCO’s excellent customer service (replacement, quick turnaround, etc)
- few people can afford these scopes who then generate necessarily few reports
- and the fact that quite a few owner dudes have a complicated interpersonal arrangement with equipment manufacturers (not just ZCO).
As in, dudes don’t want to publicly complain as that might impact their close relationship with the manufacturer or rep in the future. What if they complain publicly and the scope fails again? Will they be taken care of in the same manner?
As someone wholly outside that space, I’m just passing info along so people realize what they see
might be artificially rose-colored. This

phenomenon occurs across all brands but especially in low-volume luxury niche ones.
Also happens with gunsmiths! Like when you find out that the most-excellent ‘smith who is talked up ad nauseam on the forums turns out to be a total putz.
