    Not sure if this belongs in the Optics Forum, but this especially pertains to it being on an AR-15. Please move my thread if this is the wrong place. :wavey:

    I am looking at getting an EOTech 553 to go on my LWRC M6-SPR, and was wondering if anyone else ran one on their rifle. How do you like the 7mm raised base? From what I understand, due to the raised base, it would cause a 1/3 co-witness with the BUIS. How well does this work for you? It seems like it would be finnicky, due to it being so high. Seems I'd have to bring my cheek off of my MagPul ACS stock to get a good sight picture. How is the integral A.R.M.S mount? Does it hold zero pretty well? I understand A.R.M.S. mounts are finnicky on different rails.....any info on that?

    Thanks for all input! :wavey:

    I have 4 of them and they all work great. My unit also uses them with great success. I prefer a lower 1/3. I do not like an Eo without some type of riser especially if you are using a helmet. The riser allows a better heads up position.

    I like the 553 setup. I have used a 512 before and I definitely prefer the 553.

    Ok, well I tried the EOTech 553 on my rifle, and decided to get it. I wanted Tan, but the manufacture date on the Tan one was August 2007, and the manufacture date on the Black one was Feburary 2010, so I decided to get the one that was manufactured the most recent. The cheek weld on the MagPul ACS stock puts my eye right up with the reticle on the EOTech.

    Here are pics of it on my LWRC M6-SPR MOD 0 w/ EOTech 553 -




    Wasn't able to figure out the focus on my camera to get a good pic of the reticle.....[​IMG]

    I have a raised base and I like the lower 1/3 co-witness. Plus I figured I would add a magnifier some day and that basically is much easier then.
