Just received the EOTech 512 A.65 Rev F for my Smith & Wesson M&P15-T; and I knew there where some people seriously looking into getting this HWS(Holographic Weapon Sight), if they weren't willing to drop the money for it then getting the equivalent Bushnell; thus the reason I'm doing a quick review of the EOTech.

Theres been quite some hype over the sight since the debut of the second generation model in 2000', albeit the R&D and concept first was seen around the mid-90s. For more information please click on the following link:
http://www.eotech-inc.com/index2.php

Because it's been out for some time there have been some detailed reviews out there done in many gun and firearm magazines or websites; not to mention the many testimonies found on the manufacturer website so I'll briefly sum up.


(Smith & Wesson's M&P15-T, Troy Industries BUIS & MRF)


(EOTech 512 A.65 Rev F: Rev F - 1100 hrs of battery life with lithium AAs, increase water submersion level)

For any serious shooter, whether they be a civilian, LEO, or in the service, turn to Trijicon, Aimpoint, and EOTech for the fastest target acquisition sight system for CQC/CQB. Though there has been some varying opinion was to what works "best", it comes down to personal preference, and what works with your eye sight. I had a hard decision to make, did I want an Aimpoint ML3/ML2 or did I want an EOTech? The reason I ruled out Trijicon Reflex sight, designed originally for the IDF(Israeli Defense Forces), was I did not like the viewing area, not as large as either the Aimpoint or EOTech. However the one positive attribute that Trijicon sites offer is the tritium reticle will automatically adjust to various brightness levels in the area of the operator, that requires no on or off switch as Trijicon guarantees to 15 years. I leaned toward the Aimpoint ML2/ML3 due to my previous experience with those red-dots, knowing they work effectively, and was used to using the 2 MOA reticle. I ultimately decided to jump onto the bandwagon and try out the EOTech. The EOTech I choose was the 512 A.65, based on part because at this time I don't plan on getting night vision so having the 552 was a mute point, and secondly because the 512s and 552s both use standard AA batteries that are relatively cheap and easy to find. However the downside was the 512 uses a significant amount of "real-estate" on your Picatinny Rail (MIL-1913) compared to the 511 or 551. Another reason I choose the EOTech over the Aimpoint was that the HWS required no separate mount to allow you to co-witness with BUIS(Back Up Iron Sights), whereas the HWS inherent design allows for the perfect co-witness of the Troy Industry BUIS that come with the S&W M&P15-T. What this means is for whatever reason the optic might fail one can quickly switch to using the iron sights.


(Users without the Troy MRF(Modular Rail Forend) might consider using the LaRue Tactical QD mount for the EOTech for their flattop ARs to provide better eye relief and to increase "real-estate" on the Picatinny rail)


(Troy's Industries BUIS)


(Troy's Industries MRF)

Turning the EOTech on requires one press either the up or down brightness levels. Pushing the up will set the auto disengage at 8 hours, whereas pushing the down will set the disengage at 4 hours. Pressing both up and down brightness levels will turn off the HWS. The HWS comes with 20 brightness settings, and compared with the Trijicon if one was operating from street to house constantly, it would require constant adjustment of the brightness that might be cumbersome without practice. Even with gloves on one can easily manipulate the buttons quickly. To remove the battery one has to simply release the clamp located at the top of the battery shroud forward of the hood.


(20 Brightness Levels, Up-8hrs or Down-4hrs Disengage, Push both simultaneously to turn off, Easy Manipulation)





(Easy to find replacement for the AAs on both EOTech's 512 or 552)

The 512 A.65 reticle is the combination between the 65 MOA and 1 MOA reticle. At longer ranges one can use the 1 MOA, and at closer ranges the 65 MOA. I found that I desired some magnification with the EOTech at ranges over 100 yards, but the HWS was designed for CQC/CQB. However if one wanted to have the magnification, EOTech does offer the magnifier around June of last year or this year. Though in my opinion at the price it is offered for one should get the Leupold CQ/T MK4 with the LaRue Tactical QD mount instead of the magnifier for the EOTech. Zeroing in the EOTech is simple at 100 yards each click with elevation or windage will adjust 1/2", and half the amount at 50 yards with 1/4". I recommend using a nickel to dial in while zeroing. Moreover because of the holographic design even if the lens were shot or fractured as long as if there is some area on the lens that is intact one can still see the reticle and it will still hold its zero.

A solid review... thanks for posting it. That should help some folks who have been sitting on the fence.

I've got both a 552 and a ML3 .. oddly they both are great for closer drills. The EOT is faster for me close in, but the AP works better for 100M shots.

I am a little confused on this.

Do the red sight actually move out of the way if obstructed by snow or if it is cracked? Is this done manually or automatically?

I'm very confused as well... I've seen that obstruction feature shown on their site before, but (excuse the my ignorance here) how does this help in acquisition/accurate firing if the holo POA moves off zero due to a crack or obstruction?!? :confused:

the holo doesn't move, you move your focus point to a spot that isn't obstructed.

the reticle appears to "float" or "move"

Thanks Mike - As usual you were right on the money!
I ordered one last week and was having second thoughts about the high cost at first before receiving it - but after spending some time with it, it's totally worth the money! :)

BTW, what options are available for magnification along with the EOT HWS other than the EOTech 3x & 4x Flip Magnifiers? Variables magnifiers? QD mounts?
Was looking for something decent but a bit less costly as it would not be used too often. Any ideas, fellas?

Bushnell has a version that is extremely similar and a bit cheaper. Though you can find some excellent deals in the Equipment Exchange at ARFCOM.

Magnification, well, their is the EOT solution and the AimPoint mags. They are about the same cost (except for the EOT 4x which is crazy stupid expensive!) and then there is the "Poor-Boy" solution from LaRue. It's a cleaned up 2.5x Hensoldt sight (http://stores.homestead.com/Laruetactical/Detail.bok?no=170) that actually works pretty damn good. You'd have to put the EOT or Bushnell on a rail riser to get the sight on to the same plane as magnifier but it's the hidden deal out there right now for magnification of a 1x optic.

The recticle appears as if it is "projected" about 50 yards out in front of the sight, so you just move your head and the recticle stays centered.

I have the older 511 version on one of my ARs and I love it. But my eyes are bad, so I'm looking at magnification for mine. I actually bought a knock-off Aimpoint 3x magnifier to try, but I'm still looking for a mounting system that won't require a riser for my EOTech.

The only difference between the Bushnell Holosight and the EOTech is the armored "hood" over the EOTech lense. All other parts interchange, as EOTech actually builds the Holosight for Bushnell.

If you just need a fixed magnifier then try a single medium or maybe even a low height 30mm ring. If you're going for the flip out.. I think LaRue has a lower profile flip out that would work. The standard one requires about a 1/2 inch rise and puts you out of the absolute co-witness option.

I recently purchased a Armalite slick top version, I tossed around mounting a scope on it but decided to try my old Holosight instead. I'll be ordering the EOtech AA version next week. I had almost forgotten how nicely they work on a long gun.

Just ordered the EO 3X Magnifier (QD fixed mount) to go with 512/F on my 15T. Not that I wasn't broke enough before, but it was just waaay too good a deal to pass up... I can't wait - wooohooo!!! :mrgreen:

On a similar note, I was able to play with the EO's flagship 4X Mag (w/FTS Mount- $$$ :shock:) mated to a 511/F on a PS90 this weekend... gotta admit, that was loads of FUN!!! It lets you keep both eyes open, crystal clear, and even the sight picture is rectangular just like the EO's. It's even got a rough parkerized finish... quality stuff.
