Guess this constitutes a review and I'm not quite sure I'm posting in the right area but here goes. I've pretty much been an ACOG guy since they first came out but about 6 months ago I was doing a build with supplied optics and had to install and zero the Vortex Strikefire (red/green). I did a quick lookup and it was around $150 online so I didn't think much of it but mine is not to reason why..... Long story short, I'm out back at the range function testing the build and zeroing for 25 yds as requested. Standard A2 base up front, flat top and flip up irons behind the strikefire. The first thing I noticed was how easy operation was, that is switching on, selecting red/green dots and adjusting intensity. The line up between the backup rears and the front site post through the sure fire lined up perfectly, the dot floats right at the tip of the front sight post. The scope didn't shoot loose which was a major concern when I first saw is as there's only a single knob that locks it to the rail. There were no torque specs in the box so I locktited the screw and turned it down as tight as I dared hoping not to strip anything (real scientific, I know). Well, the locking screw was robust for sure. I ended up being able to screw it down tighter than I thought and it's rock solid for movement in any direction. Ran 120 rounds of m855 through and the zero never moved. There are covered windage and elevation screws with clicks and markings and they stay put. At a 25 yard zero it was cake to make a small aim adjustment at the 50 yd line although it was essentially unecessary. Needed to drop the dot illumination to better see the100yd x ring and it was a simple matter of pushing the bright/dim pushbutton switches in the direction I wanted the dot to go. The dot will shut down automatically after a Certain number of minutes or you can turn it off manually. When you turn it back on, it returns to the last setting so if you had it set at 50% green as opposed to 100% red, it comes back to your last setting. I personally love that little feature and I've also become a green dot fan. Long story short, I bought one myself and have had it on one of my "go to" AR shorty's for about six months and I really love this scope. Considering value/price, I really haven't come across anything that's even close. I highly recommend this optic if you are looking for a versatile, well made electronic dot optic for a flattop AR platform. I shoot it allot so it's taken it's share of beatings. The bad: 1. It literally takes an act of God to get the rear cap (soft rubber flip) on. The only way is to pull it off the scope, close it and press it back on. Very disappointing and extremely frustrating. I'll have to dig up a hard button flip for that and a hard cover for the front. 2. The operating switches are covered by a rubber, well, cover that's easy to use - your fingers just fall into place and you feel the buttons underneath. They were pretty good about o ringing everything that screws on (adjustments and battery compartment) so I assume the rubber button hood is a moisture seal. The problem is that around the 5 month mark I started to notice some cracking on the flexible rubber hood and it looks like its about to go. I'll have to look at how it's attached to the scope itself and contact the manufacturer to see what we can do. At the end of the day, it does exactly what it should and has some very nice features you wouldn't expect from a scope at this price. It continues to hold zero with very few minor adjustments after allot of firing and again, I'm pushing 62 gr bullets through it for the most part so it's getting a little bit of a kick when it goes bang. I hear they have a companion multiplier but I don't know if it's a fixed mount or swing away. They also have high rings if you need them and I think some sort of sunshade or glare reducer for the sniper in you. Hope this helps.
