Basicaly this is a heads up for anyone who owns an Eotech 557...

I recently bought one with the 4x magnifier and was soooo excited to try it out...it works fine in regular mode BUT when in night vision mode the aiming dots are NOT crisp - they are more like semi-circular dashes or swooshes. After noticing this with my NV I tryed another set to make sure it was the Eotech and NOT the NV. I then checked all the brightness levels in normal daytime mode and found that the retical has the same glitch in the 2 dimmest settings...

I notified Eotech and sent it in for repair...I included a detailed description of the problem but it was sent back to me and they said it was fine and it just must be my eyes not ajusting to the eotech...BS...

Anyway I posted the problem on ar15.com and so far a lot of other people have found thier unit has the same defect...

we have found model 557's that were manufactured Nov or Dec of 2007 do NOT have the problem, so far everyone with the glitch was produced in feb, march or april of 2008...

anyway, after several people found the problem and I took detailed pics though NV Eotech now admits "they have to do further testing" to find out where the problem is occuring...anyway at least they now admit there is a problem...

if you own a 557 you might want to make sure it works as advertised and in ALL settings...the glitch is easier to see with magnification but even with no magnification you can easily tell its not right, especually in NV mode, the rectical is fuzzy and VERY blurred...

here is some pics for referance:

CORRECT image, this is how it should look, this was taken in the 3rd dimmest setting:
