Old reliable - EOTech 510 Series 512-A65 Holographic CQB Weapon Sight

It's an EOTech 512. Simple, incredibly sturdy and reliable, and has the better part of 25+ years of global conflict abroad to be battle-proven. If you want an EOTech and don't want or need all the bells and whistles of Night-vision settings, QD, and CR 123A operation, then this is the model to go for. It is a little pricey, but it is worth it for a domestically American sight where so many other options are available that are outsourced, shoddy construction and questionable reliability.
