All good points.
If you are going to make a scope compact (short, smaller objective), it should probably be light(ish) to be appreciated by the crowd that wants a short and compact scope.
I can see maybe a few people saying that while its heavy, maybe it balances better in that form? But again - how a scope balances on a PRS rifle is nobodies concern, not when the rifles are 25+ lbs with weight kits all over it.
Makes you wonder if they built it knowing it was a compromise in a number of areas but yet showcasing a heap of improvements in others. Almost like a loss leader prototype before the improvements get incorporated into future models.
