Has anyone had their hands on the new US Optics B-Series??

I've been looking to upgrade up from my St - 10 up to an er25 , I was just now able to come up with the money I needed ,but now I understand they have a new series out and im just torn on whether or not I should get the new B25 or the older er-25 .I haven't seen many reviews out there and it's hard to spend that much money on an unvetted product. And based on the fact that they are cutting down on the objective lens size it seems like they might be cutting corners which leads me to be hesitant.
