EOTECH 512
by BobD -
I waited a long time to pull the trigger on this sight an had many Along the way. It was well worth the wait. I sighted it in at 100 yards and it did not disappoint. Very clear and super fast target acquisition. Great addition to my M4.
Good enough for our boys in Green good enough for me!

The Eotech 512 is one of the most successful optics ever to enter the field of battle or the patrol areas of our nations finest. Often imitated NEVER duplicated. You absolutely can’t go wrong with ordering one. And I am still blown away at Primary Arms price on such a high end and robust optic. The ONLY TRUE holographic sight on earth.
Great addition, setup and operation easy.

Sight came as promised, packaging was great, setup and operation was simple, instructions were well written.
Good optic!

Bought the EO tech threw it on my AR and I really liked it. The 1 moa dot is really nice for those far shots. Shot out to 200 yards easy. It has a slight haze to the dot/circle but that is expected since its a holographic sight. Was extremely easy adjusting the zero I actually used the back of a 5.56 cartridge. Mounting is really easy. I really like the wide window too, makes it easy to get on target or those awkward shots you can still see the circle.
One one every AR

Eotech will always be my preferred optic on my rifles. Built to last. I have this lower cost one on each of my rifles because I prefer the regular batteries that are readily available anyplace. Holographic over led dot for performance. I don’t have any negative comments at all. I pared them with the primary arms magnifiers for excellent mid distance capability and it just works. Battle ready for home defense or range day for short money.
Super sight with a warning
by Manuel Alen, Jr.
I've owned one since they first came out. I wear corrective lenses, the progressive kind.
The reticle I see is all squiggly. and it's my glasses. I'm used to it but it took a while.
Awesomeness pure & simple
by Gimli
EOTech can't be beat! This unit has set the standard that all red dot's try to measure up to!
You can have my EOTech when you take my rifle from my cold dead hands!
Only sight I'll use/recommend.
by Joe -
The reticle is whacky looking... But it's practical. Do some research on the reticle and how to use it and you'll appreciate this option. It's kind of large and gaudy, but it's Rock solid and the convenience of AA Batteries rather than 123 batteries is worth the extra real estate on the top.
