I can get the CompC3 with covers for $370 shipped, but then I need a mount. I can get the 517 for $395 shipped, and the XPS for $418 shipped. This is for my Midlength AR. Before Yar starts rambling about Accupoints, it's simply out of my price range. I've shot Eotechs before and really like their reticle, but have not shot through an Aimpoint. I know some of the older Eotechs had issues, but from what I've read, the new ones are good to go, and everyone seems to love the XPS. Thoughts?
