Sorry, I personally don't believe for a moment that is a military overrun optic with all that white text and graphics slathered on the top and sides (including the website URL for the company that makes (imports?) it). The thing uses a 35mm tube, so you're stuck using the rings they provide (picatinny rail sections and all). 2 pounds 3 ounces, 18" long. The ad for that item on the cover of their mailed catalog says you're saving over $2,294.
I was born at night, but it wasn't LAST night.
They will also be happy to sell you "Colt stamped mags" for your AR. Not Colt mags, not Colt manufactured mags, not mags made for Colt rifles/carbines -- "Colt stamped mags." I spent a lot of time shaking my head while browsing that catalog...
