Wow, that was fast! Ordered two Tuesday morning, PayPal -- they just arrived Thursday noon via Priority Mail. The quality looks good. High rings, single piece mount with see-thru base for using the guns fixed sights with scope mounted. 4 screws to clamp the base. Good black annodized finish. The stop pin is just a rolled pin, but looks like it can be easily pushed out and tapped if needed. I think this dog will hunt!
