Anyone have experience with Eotech's?

Complete crap. A SD gun should always be at the ready with as few manipulations required as possible. Iron sights are useless in a dark house/backyard at night.

If it's TOO dark to see your irons...then it's TOO dark to be shooting at someone you can't positively identify.

Are you an Aimpoint engineer or do you know one???? I doubt it because I spoke with an Aimpoint engineer at SHOT and he stated that the T-1 was manufactured to be left on and at the ready 24/7. Change the cheap battery out every 3-4 years just to be safe.

Even a fresh battery can fail.

What do you do for a living...or what type of crappy neighborhood do you live in.... that you won't have time to push a button before needing to shoot someone in your own house??? Is your typical response to a noise in your house to grab your rifle and start blasting right out of a dead sleep?


OP I have a couple XPS2s, one on my wife's SU16CA and the other on my Saiga. Both have 3x multipliers. I find their "doughnut of death" reticule of a circle with 2 dots to be VERY easy to utilize. It is MUCH easier to pick up then the single red dot types I have on other weapons. Simply place the large circle on the guys chest and pull the trigger with no need to look for the smaller center dot.

On both the weapons I zeroed the sights for 200yds which gives me the ability to put a round into a man's upper torso from 50-300yds without changing my point of aim.

Battery life does seem to be less then specified but the sight does indeed warn you (by blinking) WELL before it dies. While CR123s aren't exactly in every store, since they are lithium's you can stock up on them without worrying about them leaking and dieing in storage.

Others have made some very valid points about adjusting the brightness of the reticule to meet the changing light conditions. I have also found that for a more precise shot at distance I can crank the illumination WAY down when utilizing the multiplier, which will shrink the apparent size of the center dot considerably.

Mine has the circle and 2 dots reticule which really helps when a quick hold-over is needed for distance as it gives an alternate aiming point right in the sight. The center dot is for 50-300yds and the bottom is for 500yds while for 400yds I usually center the target between the two.

Even with my multiplier mounted close behind the XPS2 I have never had an issue with manipulating it's rear-facing adjustment buttons while shooting. Turning it off is a little trickier since both buttons must be pushed simultaneously and I need two hands for it but that isn't something that needs to be done in an active shooting situation anyways.

Damn, and I thought my tritium night sights were good to go. Not to mention my weapon light backlit the irons nicely as well. I guess since my HD weapon doesn't have a aimpoint I'm doomed.

Heaven forbid any other opinions are expressed here that are deviant from our resident experts.

Eotech is great, I bought a 512 at a gunshow in 2006. I used it alot the first few years then it sat in a safe for two years. When I took it out, it had a series of weird little lines at the edges of the glass. It was out of warranty.

I contacted Eotech asking how much it would cost, they told me to send it in and then fixed it for free and sent it back 3 weeks later, good as new. They obviously care about their products to not charge me a dime to repair a unit that is years out of warranty.

The optic itself is better than an aimpoint imo, it is also more advanced. Ppl like the aimpoint because it is rugged and has better battery life, but the actual technology Eotech uses is much more complex. The aimpoint is a reflex sight, the Eotech is a true holographic sight.

Leaving batteries in my Eotech for long periods of time has caused corrosion on the terminals so I generally remove batteries if its going to sit for more than a few weeks.

This reminded me of something else, unlike a red dot the EOTech has no parallax at any distance. No matter how you get behind the weapon the bullet will go where the dot is.

On the AA models this can be avoided by utilizing lithium batteries. Yes they cost more but still MUCH less then replacing an EOTech due to corrosion.

Yup, collimated before it reaches the viewing plane, which is light years beyond reflex.

I own both Eotech xps2 and the aimpoint t-1.

Love the Eotech reticle, but for some reason, when I go to BLM on a bright day, the reticle gets washed out and I am not able to see the reticle.

In the other had, the aimpoint t-1 is bright enough to be seen. Anytime I go to BLM, I leave the Eotech rifle at home and go out. I have no idea why it does that, and i've replaced the battery twice from different surefire boxes and the reticle was still not bright enough, so I'm sure it wasn't a battery issue. For indoors, it's plenty bright.

[jkonquer]

Do you even lift bro FWIW I've owned a 512. Absolutely loved it. Excellent FOV and AA batteries is a plus. I'm not tactical enough to leave it on for 3+ years anyways so this whole AP battery life is king is moot.

No Bro,
What was trying to say is that you can feel the big weight difference between with and without Eotech.

I have never had this problem and I live in the desert, so MOST my shooting is on BRIGHT sunny days.

you just have to turn the brightness setting up. although i wish eotech had some type of memory setting.

I like the 512 mostly because you can use AA batteries, In the time of real need good luck trying to find 123 / CR batteries.....

CR123 batteries are not hard to find. They are expensive however if you buy locally. They are super cheap if you buy them online and have a 10 year lifespan. Much longer than AA batteries. However, if you are a prepper, the 512 will serve you better.


Just be warned that Eotech revised the batteries to be longitude now because some of the older Eotechs were having issues shutting off under recoil. The spring for the battery would weaken overtime and when fired, the battery lost contact for a split second.

Both AimPoints and EOTechs have parallax. Neither optic has a parallax adjustment. You will notice some parallax at close distance. Try it by placing the dot on a fixed spot on the wall and move your head around. You'll notice that it's slightly off.
More specifically, APs are effectively parallax free past 50m, per the manual. EOTechs are parallax free past 100y.

[dls]

I've had an eotech 516 for around 5 yrs it's been on 3 different weapons. One battery change. Works good for me, but I just shoot cans and occasional ground squirrels.
If I was buying another red dot, I'd probably try a T-1. But Irons or a real scope are what I mostly shoot.

For all practical purposes an EOTech is parallax free since the maximum it deviates is 1.3 INCHES at 10yrds and goes down from there. At that distance height over barrel is a bigger factor on an AR platform.

No matter how you get your head behind the weapon your round is going where the dot is.

Agreed. Who the hell buys an Eotech for extreme precision work?

[Discogodfather]

The reason people say an reflex has a brighter dot than holographic sight is that the reflex optics have corrective elements for optical errors. That means its darker inherently and your seeing higher contrast because it's not transmitting as much light as a holographic sight.

I don't think darkening a sight should count for higher perceived brightness of a reticle.....

Optically I don't think there is any contest between reflex and holo, holographic is just way more advanced technologically. I'm not a ninja so I don't know which to "trust my life" with.
