I won this sight in AGI's giveaway promotion.
Very nice sight mounted on an M4, and it look very cool. It's magnification is that to what you would expect from an ACOG. A bit heavy and does not have ironsights. You will have to by a micro size red dot and place it on one of the rails. It's full metal and you can't adjust the magnification. It is a scope so you need be pretty close to it.
The large dial on top is the battery housing and the illumination dial for the red, blue, and green reticles. Three intensities for each. The reticle itself is somewhat big and obstructive especially at the brightest settings. It also only has one reticle which I don't particularly like. Think the center paragraph icon in Microsoft Word. I find having it off completely (there are range markings in your viewport like expected of a scope) or on the first brightness setting works great.
The small dial on the top and right side are caps for the screws used to adjust for windage and elevation.
The QD mount requires some adjustment to clamp securely onto a picatinny rail without wobble but that only takes 10 secs to perform. It's solidly built and works as expected. If you have a triangle front sight post, you will have to buy a 1/2" - 3/4" rail for co-witnessing or 1" to sight over the post (me). (Due to the magnification, you can actually see around the post so you don't actually need a rail but that feels very weird to me and makes the system look handicapped.)
Essentially a battery operated ACOG with rails
Rails for lights, lasers, and micro RDS
Red, blue, and green with reticles with 3 brightness settings for each
Can't adjust maginifcation (not a problem if you actually want an ACOG)
Reticle illuminated is a bit obstructive
Only one reticle and it isn't that good illuminated brightly.(So no chevron like an ACOG.)
