Hello all,

So on my AR, I would like to put a quick acquisition sight. I'm not worried about shooting six hundred yards, but I am worried about very close range to 100 yards.

I think I've got it narrowed down to two sights:

EoTech. Something like the 512ish model

Trijicon. RX01 with the 4moa dot

I like the idea of no batteries, but the eotech looks pretty clean when mounted.

What do you think?

Thanks
 
I've personally been eyeballing a Trijicon Tri-Power with the chevron reticule for the same reason: No battery needed!

Between the two you mentioned, I would probably go with the EoTech that takes AA batteries. I personally like the dot-in-a-circle reticule better than just a dot.
 
I consider the EOTech unmatched in speed of target accquisition, and I've used two of them, various red dots including Aimpoint, some 1.5x sights, irons, etc.

If you get an EOTech, get the XPS2 model, having a single battery mounted sideways makes it much shorter and is supposed to eliminate the battery contact problems that the 5xx series models are known for.
 
That's an interesting thought. I wasn't aware that EoTech's had issues with battery contacts. I would want to look into that before getting one. One more argument for not being reliant on a battery any more than you have to.

Now you made me curious, is it when mounted on anything or only of heavy recoiling stuff?
 
The "N" battery models (511, etc.) are notorious for a variety of issues, some battery related, others apparently internal. The "AA" battery models are not quite notorious, but some people report that over time the battery contacts become unreliable and the units blink under recoil. Sometimes this can be fixed by bending the contacts. This doesn't seem to be a really common problem, but has been common enough to see multiple reports. Recoil is assumed to be the cause, but reports I've read don't seem to connect it to heavy recoil specifically. More likely high round counts or generally hard use.

I have a 552 (AA model) and it's been 100% reliable for me. A friend has a 512, also 100% reliable. A while back I posted a poll here and the results were about 98-99% people reporting no problems with their EOtech. Try to look it up via search.

The XPS models switch to a single "123" battery and put it crosswise. That also makes them a LOT more compact, which makes it a lot easier to use BUIS. Also the EOTechs weigh enough to affect rifle balance, so having a shorter one that can be moved fore/aft is a plus. If you want an EOTech I would only get an XPS.

If you want ultimate reliability and good usefulness, I'd get a military grade Aimpoint and be done with it. The newish Aimpoint PRO package is around $400-410 with a mount and is all you would ever need.

I haven't used the Trijicon reflex sights, but what I've read is that their windows are heavily tinted to make the dot visible, more so than electronic RDS.
 
I really like the EOtech reticle in my 512s. However I get an uneasy feeling about them due to seeming randomness of POI shift when turning the adjusting screws. I have never had a function problem with them, but this makes me question their overall build quality.
 
I have an "N" type Eotech that was made in 2006 on my AR. Last winter while stored the batteries leaked in it. Ever since then I've been battling problems with the contacts. Like mentioned above, it blinks in and out sometimes. I'm ordering a new battery cap, hopefully that fixes the issue.

Being reliant on batteries is horrible though, I'll admit. Other than that, I love my Eotech. I pick off bowling pins at 100-200 yards while standing.

Correct. Personally, I don't like the false color. It's distracting to me and the dot still isn't that bright.

IME, the EOtechs are crazy fast on acquisition. I have an XPS3 on a 9mm AR carbine. It's awesome for anything less than 100 yards. Small profile, transverse mounted battery, and CR123s have a long shelf life so storage isn't a problem.

The real question you need to be asking yourself is what do you plan to use it for?

If it might fill an HD role, opt for something that doesn't have batteries or that you have to turn on. Last thing I want to do in the middle of the night when I'm awaken from sleep is to use fine motor control to turn on the sight and possibly adjust brightness.
 
I'm not a big Eotech fan and I love most of what Trijicon makes; but the RX01 is the exception to the rule. I'd go with the Eotech (any model) over the RX01.
 
Interesting, thanks for the opinions guys.

It's extremely possible I don't know what I don't know about. So if anyone wants to say neither, and recommend a different sight that would work for quick acquisition at close ranges, please list it.
 
The $400 Aimpoint PRO I mentioned above would be almost as good for quick acquisition (as would any RDS) but would be far, far more confidence inspiring for reliability, and it offers battery life of 3 years of constant use, vs. 1000 hours with lithium AA in an EOTech 512.

However, I do own two EOTechs and like them, I'm just aware that the Aimpoint appears superior in absolute reliability.
 
I've used the aimpoint on a friends rifle, and while I thought it was really nice, I really want an open display like on the eotech.

I'm going to take a good look at the xps2 I think. Small and light is what I'm after. Does it cowitness with the irons?

thanks all

I recently bought the Aimpoint PRO from the groupbuy on ARF.COM and am very pleased with it. With its 2 MOA dot I can achieve 1" groups @ 100 yards on my 6.8SPC. Plus it is absolute cowitness for use with your BUIS which is nice too.
 
Does anyone have any experience using the Trijicon Tri-Power? I would really be interested to hear about that since it works with fiber optics and has a battery.
 
When it comes to red dots, I've had them ALL. A big part of firearms for me is that they are my toys. I love shooting and really hate it when something makes what I love a PITA.

I won't comment about the reliability of Eotechs. Some love them, others don't. I've killed five or six 511s and 512s. I think I gave the last one away with the hopes that the recipient could get it fixed. Of course, I've heard that Eotech has made improvements, but I don't know. I will also say that the 512 is frickin' huge. If you have to get an Eotech, get a model that runs on the 123 cell. You can get the 123s pretty cheap and they have a really long shelf life. If I'm not mistaken, you have a Magpul grip on your rifle. You can buy inserts for that grip that will house spare 123s.

As far as the RX01 goes, don't even consider it. The one that I had left a lot to be desired. Heavily tinted lens, either too bright or not bright enough and funny lookin'. If you want something fast with a reticle like that of the Eotech (circle dot), check out the Trijicon ACOG TA44SG-10. The 1.5X magnification is great and it has a REALLY forgiving eye relief. I've been running one for about a year and have never looked back.

I know you've already said that you don't want an Aimpoint, but I've gotta give it a plug. I'd go with either an M3 (NV compatible) or the ML3 (not NV compatible) with a 2 MOA dot. They work well in low light, can be turned up super bright and can be seen easily on the brightest days; and if you buy two spare batteries, you'll likely never need to buy another. I've had M3s, M4s and a couple of the compacts. I just NEVER turned them off. The batteries seem to last forever. I only got away from the aimpoints due to my astigmatism. The Aimpoints are about as bullet proof as you can get. Until just after Katrina, when the gun it was on was stolen, I had one of the original Aimpoints that was anodized blue. That thing saw over 100,000 rounds on top of an open class race gun shooting major and I don't know how many other guns and was about 15 years old; and it was still working like it was the day I got it.

Buy once, cry once.

Agree 100%

I've seen the EOTechs go tits-up. They're fast and easy to use up until they crap out. Even if you do get one that doesn't break, expect the battery life to be less than 200hrs, as opposed to the advertised 600hrs.
The XPS models have a fatal flaw, in that the transverse mounted battery is not sufficiently supported. There have been reported issues of the CR123 batteries cracking in the middle due to lack of support, and then leaking battery acid into the optic. That in turn completely destroys the optic.

Trijicons Reflex sights are heavily prone to washout. If you are in a dark area looking into a bright area, or moving from inside a structure or enclosure to outside, the reticle will disappear. Also, if you are outside during the daylight, and you look at a source of light or reflection, you will have washout. As stated, the reticle is never bright enough, or too bright to use. I've found that 99% of the time, it's not bright enough. I have never used a Reflex sight that I've liked, and I've used both the 1x24 and the 1x42 models.
ACOGs are nice, but not a CQB optic by any means. If you are going to be at short to mid range, the 1.5x models work, though I believe them to be far too overpriced to be feasible. I think that 1-4x scopes are more feasible due to better focus and more utility. For the cost of an ACOG, you can get a US Optics SN-12/12R, or SN-4S, and you will get better glass and a selection of reticle options.

Aimpoints are the best RDS on the market, hands down. They are the only sights that I've never seen fail due to malfunction.

I've used all of them, and the Aimpoints have always stood out as being the best option. ACOGs are a different story and a different role (DMR vs. CQB).

This is something I have been wondering about, as I have astigmatism. Were you getting blurry dots or misshapen dots with the Aimpoint?
 
I'm not Tony, but I also have a degree of astigmatism. In dim light, all red dots look like amoebas. In bright light, they usually look pretty round. I don't like the amoeba view but it doesn't really affect the usefulness to me much - in dim light you won't be shooting 1 MOA groups anyway.

I do not get the amoeba effect with any conventional optical sight, including the ACOG (I have a 1.5x ACOG), nor do I see it with the EOTech reticle.
 
Buy once, cry once indeed.

Thanks for the advice guys. The more I look and hear, the more it sounds like an aimpoint PRO is just the way to go for my purpose. The PRO should be just fine right? Time to try and find a good price on one.

Don't you love it when you have it narrowed down to two and you pick a third? ...The beauty of THR...

M&PVolk, yeah I was getting the "comet" reticle. In practical usage, I guess it doesn't really matter, but like I said, guns are my fun, among other things, and I just wasn't willing to live with it.

The one advantage to the small acogs is the size, or lack thereof.
 
Aimpoint is my favorite hands down. Eotechs actually consume battery life even when off which makes them terribel for home defense in my opinion. Aimpoints on the other hand are indestructible and the batteries last forever.

I havent had a trijicon yet though.
