Skip it and buy an Aimpoint Micro. The Eotech sites have low battery life and questionable durability. You can get an Aimpoint H1 Micro with a Daniel Defense mount for 10 bucks cheaper.

They use a holographic system instead of the LED of the Aimpoint, yes the Aimpoint has longer battery life, but I don't consider 1,000 hours (lithium AA) short.

If you say so, sources?

Personally I like them both but greatly prefer the reticle of the Eotech, plus the light can only be seen by the user, the aimpoint's like most red dots, is visible forward.

1000 hours is a lot shorter than 50,000+ hours.
And it isn't just the battery life but also the auto shutoff. I have talked to many a person who needed their rifle only to find their issued Eotech had turned off.

Yes I do say so. And so do a lot of people who know far more than I do.

Found those two in about 30 seconds.

My instructor has an Eotech he put on a .22 AR conversion he uses for his kids. Fails constantly. Has sent it back a couple times.

Guy I train with has an XPS on his issued rifle. It has failed and been replaced numerous times. Can't stand up to actual use. He wants to switch to an Aimpoint but no go so far in his unit.

Another friend of mine had one that would turn off under recoil.

I have had a couple that have been fine but never ran them hard. Currently have a 522 I am thinking about putting on my M&P 22 but will probably go with a PRO instead.

If you are going to give information don't give wrong information.

I just checked with an M2 and an H1. Both when turned up to full power in a dark room were only visible from about 3 feet away in front and only from a very narrow angle. Any further away and it could not be seen.
 
I have an eotech and I like it. I am still on the same battery and I have had it for about 2 years. I will say that most of that time it has been sitting and not used, but as of 2 days ago it came right on for me.

I think that it would be a good idea to change the batteries every so often depending on use. Do it regularly and consistently, so dead batteries wont be an issue. As to durability, mine has taken a few nasty knocks and is none worse for wear. For both these issues, back up sights can help.

All the aimpoints I have tried in store the LED light is visible forward, Now mind you I haven't tried them all I'm sure.
 
I have never seen an Aimpoint that was visible forward. The M2 is the oldest model on the market right now and it doesn't' show forward as I said above.
 
I recently got a 512 for my AR. I really like the 1MOA dot. Two eyes open aiming takes a while to get used to, but it is really REALLY nice when you get adjusted, makes for fast target acquisition.

As for the whole EOtech vs. Aimpoint thing that has stirred up. I don't think you can go wrong with either.
 
Never an issue with my XPS2. In fact, just pulled it out and fired it up....dang, battery was just fine.

My opinion exactly, each have their pros and cons (more pros than cons really). Currently I have an Eotech on my MSAR but plan on putting an Aimpoint on it instead and move the Eotech to the RFB. The design and shape is the determining factor.
 
As far as I can tell from the EOtech website, the only differences between the EXPS2 and the XPS2-0 (which I have) is the EXPS2 has a 7mm raised base and the buttons are on the side instead of the back. That being said, the XPS2 I bought used a few years back is still going strong and problem free and still using the same battery.
 
I have Aimpoints and Eotechs. You can't go wrong with either. Each Aimpoint has it's niche. But the only Eo's worth getting now are the XPS2 and 3. I feel that they have really stepped up thier game. So now once again, Aim vs Eo can be a daunting choice. (get both?)

The XPS2-0 I have, is by far the nicest Eotech I've ever used. Improved battery life (apparently) and feels much tougher with the simpler and smaller battery compartment. I don't think battery life is much of an issue anymore. When your Cr123 battery gets old, just chuck it into one of your flashlights and put a fresh one in your Eo

The Eo is a hair faster than an Aimpoint ML3 or T1. But the Aimpoints are more durable, button up with nice lens covers, and are quicker to adjust brightness on.

The Eo has a better FOV and smaller dot. But the 1moa Eo dot is not 4 times smaller than the 4moa Aimpoint T1 dot. In real world use I feel the dots are alot closer to each other than the specs say. But the Aimpoints dot, is in no doubt, larger. Maybe about twice as big. An Aimpoint Comp Ml3 with the 2 Moa dot, deosn't have a round dot, but more like a jelly bean. On higher settings it's a death squid. But if you're that picky on dot shape/size get an Trijicon mini ACOG or 1-4x Accupoint.

You have to remember to turn your Eo on at night. Up button for 8hrs, down for 4hrs. While the Aimpoints can be left on forever. Having to take 30 seconds of my evening up, turning on my Eo is much more of a pain than battery life. (maybe one day they'll add a clock to these things so they can auto power up when I'm home)

So with the Eotechs I leave my BUIS flipped up, incase I forget to turn the optic on. If I'm just training or competeing I leave my BUIS down.

Both are best in Larue tall QR mounts for lower 1/3rd cowitness. I feel that the Eo is too low mounted flat to the top of an Ar15 for CQB use. A QR riser helps alot. Regular carbine duties?, probaly fine mounted flat, regular cowitness.

What rifle are you planning on using it on? What purpose?

I haven't tried the EXPS-2 with integral QR mount set for lower 1/3 cowit. I'm not a fan of the side buttons. I slop my carbine on the ground to often fo that, I think. But I haven't heard of anyone tearing a rubber button cover on the side button models. I'd imagine the side buttons are more of a nightvision thing. Tough reaching the rear buttons with a PVS14 in the way.

My ML3 is visible forward. But if you manage to see that end of my rifle you have bigger problems. Besides you have to really be looking hard into the business end of my ML3 to see the LED.

I don't even think that a PVS14 3rd gen nightvision would pick up that light at 50 feet. It's like trying to see the tip of a needle. But at least I have another neat test to do next time I get my hands on some NV stuff to play with. See if I can see an Aimpointg LED at night at a decent range. Hopefully someone will beat me to it, I don't have acces to any NV gear right now.



I also forgot to mention: Even tough you can leave the Aimpoint CompM3, M2, ML3, ML2 on forever. You should remove the battery every couple of months, make sure it's clean and then put it back together.

I've noted that a few Aimpoints have a habit of being dim as they come out of the safe. Removing and reinstalling the battery fixed it every time. Possible unseeable corrosion of the battery chrome? Who knows?

Do you wear contacts or glasses? If you lose thos, the Eotech ends up with a 100moa basketball of death reticle. Still fine for CQB, useless at longer ranges. While the Aimpoint will have a much smaller blur. (Not like it's likely you should have a good reason to shoot at something too far away to see anyways)

OK, let's change it up a little bit.

Any foreseeable problems with mounting it on a G3? Picatinny rail mount is on the way from RTG.
 
Forget 'em both and get an ACOG TA44SG-10. :D

No, really. I do like the reticle of the Eotech and it is arguably faster for up close target acquisition, although I would imagine that you can be just as fast wtih an Aimpoint with training.

My personal experience tells me that Aimpoints are much more reliable. I know that the new battery compartment on the 123 models helps to do away with the former trouble with the battery contact springs, but unless they did a significant redesign on the internals, I believe that there are still weak points in the system that would make the sight recoil sensitive.

Another thing that I really liked about the Aimpoints was that you just leave them on and don't worry about it. When you pick the rifle up, there it is.

For me, I found the best of both worlds with the little ACOG. It's always on and dependable.
 
"For me, I found the best of both worlds with the little ACOG. It's always on and dependable."

That is what I would love to have on my AR, but I am still in school so it will be awhile..
 
Tony Angel brought up a huge point......."recoil sensitive". I'm planning on putting this thing on my PTR-91. Lots of recoil. Will I just end up destroying an expensive optic?
 
That's why I brought up the internals. I'll admit that it's been a few years since I messed with Eotechs. I had six or seven of them, mostly 511s and 512s and killed them all. Two died on top of AR15s in 5.56. The rest of them died on top of a Beowulf .50. Some lasted a couple of hundred rounds. Some lasted less than 20 and the problem wasn't with the battery compartment.

Isn't there a minimal effective range on an ACOG? What would be the max useful range of an aimpoint without a magnifier?
Click to expand...

A little bit longer range than you shoot with Irons. Maybe about 20-33% better range than irons for me. Mostly because a dot is easy to aim, deosn't need lined up.

So if your comfortable shooting irons at 300 yards. 350-400 should be no problem with a 1X, 4moa or less dot.

If the ACOG reticle is bright enough, and not getting washed out by lighting conditions or the transition from a bright room tyo a dark room, your off optic eye will pick up aiming and you'll see eveything including your dot/triangle/doughnut at 1x. So ACOGS can work really well sometimes close up. But have scope shadow and other scope related issues that a Reddot deson't.
