Tried it in the demo room today. Takes a bit of getting used to. The D-EVO is just the prismatic 6x non-illuminated scope mounted on the side. There is no battery source needed despite the look of the scope. It must be used with whatever holo or red dot optic of your choice. As GT says, there is a veeerrry small range for eye relief. 4" is it. You also need to have a 1/4 inch higher cheek weld. The rep says instead of just doing your normal cheek weld, pinch your cheek fat rolls and " sit" the stock on it and that would give .25"
I found it very difficult to see the 6x while transitioning between both. Since the red dot is now the primary optic, the glow really distracts from seeing the scope. The rep says it's a matter of your brain registering the effect and the rest is practice, practice, practice. This device does not encourage any sloppiness. 1-2" either way and you won't get a good sight picture from the glass.
Once the red dot and the D-EVO are co-witnessed, and you can actually see the glass clearly, it is quite a cool concept. Aim your red dot at any distance. If the target is too far, look down and the D-EVO will be right on it with a 6x mag. The optic goes to unnamed buyers to start and will be released to the US market in April. Not sure when it comes up here.
The other " new" optic is SIG's Electro Optic. In simple terms, it's a battery powered red dot with a cool reticle at fixed 4x30 mag but in a rugged package and not a traditional scope tube.
In all honesty, the Elcan Specter 1-6 or 1-4 beats them all. The quick 1-4/6 lever is the simplest system of all of these. And they're Canadian!
