Does anyone have any experience with this sight? ???
I don't have a 557, but if it was elevated in and of itself 0.3" on an XCR, wouldn't it be 0.3" higher on any rifle it was mounted on? It would still only be .4" higher on an XCR than an AR correct? Perhaps you meant since it is elevated higher than the other Eotech's (512 etc...) that it would be 0.7" higher than the 'normal' sight line on an AR (using a 512 or something)?I have, and its a good optic. Keep in mind though that the XCR rail is .4" higher than the AR15 rail, and the 557 is elevated nearly .3", which would put the 557 .7" higher on the XCR than it would on the AR15. It would be very tough to maintain consistant cheek weld lock up while shooting with an optic that high
Standard height Eotech's (512/552 etc etc) put the reticle at the "correct" lower 1/3 position with a nice and tight cheek weld out the box. No extra mounts or risers needed.
