The See All Open Sight is a pretty unique product, and I jumped on it early in 2014 for my “Ultimate Mosin Nagant” build, then followed up with a review on the sight itself. In response to customer feedback, version 2.0 has received numerous updates to nearly every aspect of its design . . .
Consumers’ biggest sore spot with the See All was its mounting system. It had a fixed groove machined into the bottom and had to slide down the gun’s rail from the end to wherever its final destination was (which isn’t actually possible on some firearms), where it was then fixed in place via a set screw. All of this is gone, and the new version mounts to a Picatinny rail via a more typical cross-bolt clamp system.
As V2.0 is sleeker and lighter, See All is milling it to fit in the rear sight dovetail of various pistols. Five dovetail-fit pistol models are going to be available right out of the gate (I believe 1911, GLOCK, M&P, XD, and FN).
For 2016 the reticle has been changed from the delta (a solid black triangle) to a more standard crosshair. [EDIT: the crosshair is a new option, but the delta will still be available.]
Also available is the option of Tritium illumination. A Tritium vial is embedded in front of the fiber optic slab, and sets the whole FO aglow. See All towed a trailer down to range day so you could step into it and close the door, and the sight worked as advertised in the dark.
