If you have an Eotech 557 made in feb/march/april of 2008 you will want to check it. Many people, including myself, have found that in all night vision settings AND in the 2 dimmest settings the rectical glitches, the dots turn into elongated swooshes...Eotech admitsto having to do testing to figure out whats going on but has not fixed the problem yet...
