I just received a Kit # 4 on Friday and my impressions are generally positive. My biggest concern was the weight; I am a big ACOG fan and you will have to pay a weight penalty for the better adjustable scopes. Right now it’s mounted on a rifle that sported a TA11 with LaRue mount, so it’s only about 3-4 oz. more.
Glass clarity is quite good. Appears rugged and well done. With the diopter properly adjusted, the milliradian hash marks are clear and visible against a light background without illumination. Although my eyes are astigmatic, I do not have any problems at all with the illuminated reticule. (Aimpoints did not give me a problem, but the older Eotechs – 552 – drove me nuts.)
Although the illumination battery life is supposed to be very short – about 70 hours or so, that is not a problem. The reticule design is what attracted me to this scope and I am happy with the setup. I like the “old school” concept of using heavy bars to point to the center of the scope, and then a relatively empty space indicating the aiming point. Brush hunters used this system for years before illumination came along.
Although I occasionally think “I should have gotten the DoD reticule,” I doubt I will miss it at all. At lower magnifications, circle reticules slow me down because I try to frame the aiming point inside the circle rather than just let the three heavy bars point to the thing I want to hit. I don’t want to look at the reticule; I only want it to tell me how to align the rifle. The ToD is a faster system, I think.
Also, if you are looking at small distinctions, the open space indicated by the interior heavy horizontal and vertical bars is smaller than the interior of the circle, meaning that the T-reticule is potentially slightly more accurate for fast, close range work. At 4x, the circle is purposeless.
As Failure stated, the sight is not really meant to use illumination all the time. It does not need it. Rather, illumination could be handy in low light situations and should be an option in your bag of tricks, not something to rely on. Similarly, as stated above, the sight works best as a 1x sighting device, with the potential to push to 4x if it will help.
Due to other commitments, it took me all weekend to get the scope mounted and properly set up. Adjusting the diopter took me a while, mostly because I was stupid and tried to do it when the light was less than I needed, and, because I thought I could do it quickly. I knew better, but …
A note on placing the scope in the Bobro: At first I was surprised to see that some people had not pushed the scope all the way forward in the mount, but realized once I had my hands on the scope that the large illumination knob on the left made it more advantageous to place the scope slightly back by about 3/4" in the mount. Even so, with the mount placed with one slot showing on the top of the upper, I could get a good cheek weld with an A1 length stock. When I placed the mount on a different carbine with a collapsible stock, I could get an acceptable eye relief with the stock set on position three (from the receiver) and the mount placed as far forward was it could go.
Now, if I could only get enough time to shoot the thing. Maybe this week.
ETA: The scope in the # 4 Kit Bobro mount (very nice) clears a Troy flip-up by 2-3 millimeters, and will probably clear a few others others, without the caps. But, I noticed that the large ocular bell and the BC caps will probably provide have contact with PRI and Magpul Gen I rear sights. That measurement will have to wait for another day.
