That is correct. The ADM mount held up to everything except for the jeep running over the optic (somehow the mount became loose) and a piece of shot getting wedged between the rail and underside of the mount. The piece of shot is hardly the mounts fault, and since a 3500lb+ jeep ran it over, I think it held up rather well. FWIW, I won’t be replacing the ADM mount because of this test; I was just curious if the Larue mount would have prevented the loss of zero. My guess is as good as yours.
thanks for this, very cool to put your own cash on the line, I have a 552 and a 553 and like them both, was thinking about an XPS for the next rifle, this pretty much seals the deal for me.
OP,great job!Makes me feel good about my purchase 
.
I was looking at the XPS and thought about saving for one. Now I know I will save for it. Getting that EOtech seems more logical then spending money on a lesser one like a truglo or barska or any other 150 or less RDS. This has helped me decide as I am not liking the Aimpoints to much. Not saying there less then an EOtech or not in the same class of manufacturing as one. I just don’t have any experience with them. To bad it doesn’t come in OD green as That’s my main color for my AR.
OP thanks for torturing yours for us and your rifle wish I had that kind of disposable income. I would be torturing a lot of things.:lol:
I have seen a lot of posts saying that this test sealed the deal or they are choosing X because of this test. I encourage you to not buy this sight because of this test, but just add it to the list of positives about the XPS. This is a sample size of one, and it doesn’t represent every XPS out there. If this sight fell within one standard deviation of the mean value of the sights, then it is a good indicator of the durability of the sights.
I want everyone to understand that every sight has its pros and cons as well. The sight is durable. The sight turns itself off after 4 or 8 hours. It has a really nice reticule with the large 65 MOA circle and the 1 MOA dot. It also weighs twice as much, with the ADM mount, as a T-1 and Larue mount (337g and 165g respectively). The sight window is larger and allows for easier head placement on the stock. The sight also has 600 hours of battery life compared to the 50,000 of the Aimpoint.
I state these facts because a person shouldn’t base their optic choice because of x or y or z, but take in the whole package while considering optic choice. This EOTech does 90% of what I would like it to do. Please, for the love of God, think for yourself instead of parroting information about Aimpoints or EOTechs and think for yourselves. Don’t like something because it is the latest cool guy gadget, but because it works for your mission and your parameters for what you want an optic to do.
I just hope that me bashing the sight against a tree, shooting it with a 12 gauge, running it over with a truck, and throwing it out of a truck at 20 MPH dispelled some of the myths that EOTechs are not durable. It is a durable sight but it also has drawbacks that the Aimpoint does not. Weigh the pros and cons, all of them, before making a decision about what you stick on top of a rifle.
If anyone asks me what I would want the perfect optical sight to be, for the average user, I would say an ACOG would solve so many problems because they can be used up close, far away, and everything in between. The ACOG is also a compromise, but I will always have at least one sitting on a rifle unless something else comes along that is a better hammer.
Don’t follow the crowd; think with your head and decide what is best for YOU and YOUR mission.
Well said.
I went with the EXPS 2-0 because I wanted to try something different. I believe that the EOTech’s greatest difference from other optics is the reticle. I am glad to see that the this particular EOTech can take the kind of abuse that it has; of course, the military has been using EOTech’s successfully for some time, and we can only imagine the abuse they take.
Great test, however I don’t really remember the problems with Eotechs being the things that were tested. Seems like most of the reported problems were related to the factory mount coming loose and battery issues to include short battery life and the reticle dying from bent/broken beattery contacts.
The battery compartment issue has been solved by having a transverse battery. There is a pic of the battery cap taking a big hit somewhere around here, and the sight still turns on.
As for the factory mount, I was able to get more torque on the screw through the allen bolt instead of the thumb screw. It hasn’t come off yet.
As for short battery life, it is the nature of the sight and is a negative about the sight in my eyes.
Maybe.
There may be an issue with lateral force exerted on CR123 batteries. It may be a battery issue, repetitive recoil cycle issue, or unlucky event, but there have been verified problems with more than a few XPS and EXPS models. There are only a few other optics that have lateral mounting of CR123 batteries, and they really aren’t used for high volume shooting.
What I am looking forward to is years of accumulated observations and data on these sights. It took us a while to figure out that the first wave of EoTechs had issues, and it will take a while to see what there are really doing.
The test wahoo did is pretty decent for demonstrating gross toughness, and I do know some that had doubts about the EoTech in that regard, and knowing the pros and cons of the sights in the market this might sway them back toward the Eo. There is more to optic lifespan than being dropped, smashed, dragged and fragged.
One more minor thing: testing for zero shift.
This should be done on as small a target as you can possibly hit (if you are shooting steel at distance), or tracked on paper. An 6" piece of steel at 50 yards will permit almost 6 MOA of shift before you would know. Not what I would call “retaining zero”.
I agree about the zeroing. It was the best I could come up with with the materials on hand and brevity for the videos sake. Idealy, each test would have had a mechanical rest at the original 100 yards on paper and using a pair of calipers to measure zero shift. It was good enough for Vickers to say that it was combat accurate in the DD test though FWIW.
If someone wants to donate another EOTech or Aimpoint for this test, I will gladly do it! 
I did a lot of reading before i made my choice,and i’m happy with it.EOTechs are making a big comback with the XPS series for sure.As for the batteries being a problem they way they are mounted,i haven’t seen/read of that being much of a problem.Nothing like with the inline mounted styles.The built in QD mount,reticle and 123 cell is why i like it better than an Aimpoint.On top of that it’s AMERICAN MADE!
I think that with the EOtech being a “true” holographic sight, your trade-off is a reticle you may prefer for shorter battery life. The Aimpoint can stretch it’s battery life out so far because it’s just a single LED being powered, which are energy-efficient to begin with. Producing a hologram at different power levels is what gives you both the classic EOtech reticle AND the shorter battery life, even if EOtech has the same/better chipset technology or whatever.
To the OP, thank you for being willing to abuse your gear for this test. It just makes my decision of which RD sight to get even harder. Now I’m thinking EXPS2-0…?
OP,
For non warrantied repairs, Eotech will charge your $169 and completely rebuild your optic. A SWAT guy came into my work with a hilariously beat up 552 from 2001 or something… absolutely no tracking and the hood was tore the heck up.
Eotech completely rebuilt the optic from the ground up. It’s a easy process to request a rebuild, just give em a ring and they’ll give you a RMA#
That’s good to know. Thanks for sharing.
Of course, I don’t shoot enough currently to put my optic in that condition.
EOTech does have AWESOME customer service!I’d send them a link to this thread and ask what they’ll do.They may very well like this!
Can’t hurt to try, but I don’t think aggressive testing will be counted under warranty!
:lol:
Just rest well knowing you can get your optic restored to like new condition for a lot less than buying a whole new one.
So… If this is true, the question now becomes “how much will it take to stop an EOTech?”
Yeah, you might as well go the full Myth Busters route and keep going until it breaks down. I’m sure I’m not the only one who’d love to see that. Hell, I’ll even toss 5 bucks into the proverbial hat to get your Eo rebuilt after it goes kaput.
If you’re going by the DD test, you still can drop that sucker from somewhere really high, and everyone’s favorite, blow it up, too bad the 4th just passed :D.
What would be a really good idea is water submersion and firing the hell out of it until the battery compartment or battery fails. Maybe you can lend it out to as many friends as possible to subject it to as many rounds and calibers possible.
When it finally gives out send your money and a link to Eotech and see what happens.
Thanks for the testing, that goes above and beyond the usual homebrew of effort. Now, what about the rest of the items on the AR? Foreend, stock, sling mounts and anything else that’s not an integral part of the upper and lower? Anything break, come loose, become unusuable?
