I have a Burris AR332 on my AR10 carbine. I also have the quick release mount and ARD (killflash). It’s a nice little,rugged, compact package...5 reticle brightness settings in green and 5 in red. When it’s off or the battery is dead you still have a black, etched reticle. Early production had some issues with canted reticles, but that’s been overcome. The BDC is graduated for either 5.56 or 7.62. You just have to memorize the tables to use it for it’s fullest potential. At fixed 3X, it’s suitable for CQB drills, but still enough magnification to help out nicely out to 500m or so with man size targets, but not by any means a precision target scope. When I first bought it a few years ago, I stupidly over-torqued a mounting bolt. The Burris customer service folks were great, and sent me two for free the same day I called.
Thanks. Good info.
