I am looking to purchase an EOTech Holographic Sight for a UTS15 shotgun. Does anyone have a recommendation on a specific model. I am leaning toward the XPS2, which as near as I can figure out, is the newest model, and it is also the most compact. It is running around $520. It is not night vision equipment compatible. To get that, I would need the EXPS3, about $100 more. There are also less compact - and possibly older models like the 512 and 552. I think they take different batteries, AA's vs 123's.
Anyone with any experience with these, I would appreciate your comments. Or alternatives.
