performs nicely

Was going back and forth between ACOG with an RMR dot on top along with the Eotech. After shooting both, eventually went with the Eotech configuration. Installation was incredibly easy. Just an FYI whenever you put in the holographic part, be sure you push down the unit and forwards on your railroad system as you move down the fast release.this ensures you get a solid match and it keeps zero better. Otherwise, while it'll be tight.there's a little bit of space for slop along with a zero shift should you lose the rifle or any other large jolt to the rifle. The magnifier unit performs nicely and is crystal clear. I suppose what I like best is to get short range work. Say 50 yards and not as the magnifier can be flipped over and only the holographic unit utilized. Since both are intended to be used with both eyes open. Theoretically both the Eotech along with the ACOG should be the same; however, I find for close-in type shooting, the Eotech only seemed to have the advantage. Among the most significant benefits of this was that you could reverse the magnifier to the side and use your BUIS without a problem. Without a doubt, if you're going to attempt to shoot 300 yards and much more, the ACOG likely will be a better option, but if I understood it was going to be a 300+ yard scenario, I'd opt for another caliber and rifle. Still, I'd no problem getting hits on 12 steel 100% in 200 yards. A lot of the functionality of the sight system at longer ranges is going to factor on how good your eyesight is at longer ranges. The magnifier is, in fact, 3.25X, therefore hitting a shape at 300+ isn't a problem provided you may see it in the range. I'd say that shooting at 500 or more. Well, can it be possible? Sure, but this isn't the main designed function of the system. For what I consider the use of the AR for, 400 yards and less. And mostly 0 to 300 yards, this is a fantastic system. Another FYI. The four dot reticle does look a little overwhelming whenever you flip the item on.and without the magnifier it pretty much looks like a straight line or a post. Two things here.the unit turns on at par 12. Which is bright. Turning down the brightness helps when utilizing the magnifier. Second. Eotech does say that to leverage the 4 point system you need to use the magnifier. And you do. When utilizing it for close in, I only use it as sight post as opposed to attempting to pick out points and it works great. Besides. The upper point, at least on mine is sighted for 50/200 yards. And me trying to shoot at a target beyond 200 yards.well the magnifier would be in use for sure.
