I am reposting this, my original post was a month or two ago on sigforum:
A few months ago I picked up a Trijicon Reflex II. I got it because the price was right and when I examined it I was impressed with construction and I liked the battery-free option.
If I were a cop or military doing any kind of entry into buildings I would not want one on my rifle. Why? Because the reticle can and does washout if you are in a dark room looking out at something that is brightly lit by the sun. A bright flashlight shining on a white t-shirt is enough to make it hard to see. Personally I am not concerned with this for a few reasons. First, I am not on a SWAT team, and second, I can use my front sight post as an effective aiming point if I ever have to use the rifle for defense inside my home.
That being said, outside it is an excellent option for quick acquisition. I have heard it said that the optic is useless in bright sunlight. I don't know how that can be unless someone had a unit with a defective or broken fiber optic. The fiber optic light gathering works extremely well. As long as you are outside it gathers enough light on cloudy days or bright and sunny days that it won't washout against any background. Inside a building and looking out at objects or backgrounds with high albedo is a no-go. If you are strictly shooting outside it is an excellent optic for a hobby or sport rifle out to 200 yards. I can put hits on a target out to 300 yards but the 12.5 MOA triangle is a bit imprecise once you get that far out. 0-100 yards it is excellent.
If any of you have kids and want an optic that is great for training on a 22lr AR or a Sig 522, this is a very simple point and click interface. My nephew got to try it out, and he loved it.
I use it for 3-gun, and while it is far from ideal for shot over 200 yards, I think it is superior to a 1-4x scope for everything out to 100 yards. I shoot with both eyes open and it works great.
A little magnification would really be nice out at 300 yards+ and I am trying to decide between a TR24 accupoint or shooting irons with the 3-gun rifle I am in the process of accumulating parts for.
It is hard to take pictures of a scope reticle, but the triangle is centered in the sight hood when I have a proper cheekweld.
I understand that the battery life of Aimpoints is tremendous, and they are absolutely acceptable for hard use. But it is still nice to never need a battery for daylight shooting. The tritium will eventually fade, it will still be a good sporting optic.
Another nice thing about this optic. If it gets muddy or extremely dusty, the manual recommends cleaning it by dunking it in cold, clean water.
I was shooting in the rain the other day. A friend of mine took his cheap red dot off his AR because he was afraid to get it wet. This thing IS tough, even if it has other shortcomings.
On a cold gray day, it still worked great.
I think the optic compares very favorably with the Eotech and Aimpoint for anyone who doesn't use their rifle to fight bad people. There are mounts available from Trijicon for Sig 55x series rifles, Picatinny, and Weaver rails. The reticle is available in various dot sizes, and the triangle like I have.
They have updated the Reflex sight with a wider objective, although since I shoot both eyes open, the objective on the II series is more than wide enough for my taste.
