These are the model with the bk-7 prisms, blue lenses, tripod adapter.
Only had these a few days, spotless, nicely collimated.
They were backordered, bought another pair from a different vendor before these ones arrived. I'd keep them anyways, but the wife just doesn't see it that way.
I'm asking $75 (US) includes shipping via USPS within CONUS.
Feel free to contact me if you have any questions.
