I bought two but sold the rifle before mounting it. Great scope, duplex cross hairs, water & fog proof, 1" tube with rings. Amazon sells them for $59.95 + tax. read their reviews, then buy mine. They are tough I have on my Henry Homesteader 9 mm carbine with no problem. I can't say for sure, but I suspect it would also be fine with a low recoiling 5.56.
