I have a couple of questions about EoTechs. I am trying to decide between a 512, 517, of XPS.
Battery life and NV aside, do they all function exactly the same, whether it be a 511, 512, 552, XPS, etc.? Do they absolute co-witness without a riser (XPS & 512)? Do they lower 1/3 co-witness with a 7mm riser (517 has this built in). I am really thinking about the 517 because I would prefer a lower 1/3 co-witness and would also prefer the buttons on the side. Thanks! |

safehaven,
There are some differences you need to consider: Size: The XPS will leave you far more rail space (if rail space is a consideration) than the 512 or 517 Co-witness: 517 - lower 1/3 co-witness, easier to operate with a less obstructed view XPS and 512 - absolute co-witness If you are even considering a lower 1/3 co-witness the 517 is a great buy. It has excellent run time off of (2) 123 lithium batteries and side mounted buttons if you plan on using folding rear sights or a magnifier down the road. The 517 is also affordable! |

The 517 is the AA model. The 516 is the CR123 model. Both offer lower 1/3 co-witness. |
