Love to hear how the SeeAll works out.
Got it on Thursday, mounted it, and took it to the range on Friday. I like the way it looks on the gun, as compared to the red dot. It's certainly a high-quality piece. The body appears to be machined out of a solid piece of aluminum. The lens looks high-quality as well.
Unfortunately, I can't say that I liked
using it better than a red dot. It's kind of a strange thing. If you shoot with only the dominant eye open, you can only see the point you're shooting at with difficulty. When sighted in, the gun is always pointed towards the crosshairs, but the crosshairs are etched on to non-transparent plastic.
The system produces very good windage results. At 50 yards, I didn't have to try very hard to get the shots within 1" of vertical line I was trying to shoot. Elevation is another matter. To see where the point of impact will be, one moves the crosshairs as closely as possible to the top of the sight picture. In just the right spot you can see both crosshairs and what you're shooting at in the dominant eye, the crosshairs through the lens, and the target looking over the lens. But neither crosshairs nor point of impact is especially clear like that. It's like they're fighting, and to see one more clearly, the other has to suffer. My groups on paper ended up being vertical strings, in large part because it was hard to see the center of the target and the top of the crosshairs clearly at the same time.
If you try to shoot with both eyes open and use your other eye to to see the point of impact more clearly, you have to make sure your eyes stay aligned with each other. I found this easy with the Seall at 25 yards or so. I did some quick shooting, and it was fast and easy to acquire the sight picture, and easy to hit with it. It was doable at 50, but it was a lot easier to hit a target like a clay on the berm than to shoot a tight group on paper. It turned out to be a real challenge for me at 100 yards. A few times when shooting relatively quickly and trying to use both eyes, I got the elevation off by a few
feet. Obviously my left and right eyes did not stay lined up.
It's a cool idea, and this would make a nicely compact set of backup sights for a tactical rifle, for older eyes especially. But I don't think it's my cup of tea for recreational shooting. I switched the gun back to the Holosun red dot.
