5.0 Rating EOTech Always the best - 4/3/2014
Reviewer: Old Army Dude
I love EOTech sights. Always have since I first used them in the Army. This sight sits slightly higher than the 512 which is basically the same one I used in the field giving you a lower 1/3 co-witness. Whereas the 512 gives you center co-witness. They moved the buttons to the side to make them accessible if you mount it close to a rear sight or use a magnifier. They also carved away the lower portion of the battery box so it will fit over standard hand guards giving you the option the mount it more to the forward area of the upper receiver allowing you to mount a magnifier without the need to change to a quad rail hand guard. But if you have a flip to side magnifier or use a magpul rear sight the rear mounted buttons on the 512 are still reachable with no problem. Get the less expensive 512 if you want center co-witness, use a magpul rear sight, or have a flip to side magnifier. If you like having side access to the buttons and do not mind lower 1/3 co-witness, spend the little bit of extra cash and get the 517.
