The mount is made in the USA.
Clark, You are so right about the P-223 3 BDC Carbine Scope. When I first saw it at Shot Show I wasn't sure what to make of it. Then after about 2 hours of showing it to folks at Shot Show and hearing what they would use it for my eye's opened to what a great idea itreally is. So many guy's who are real shooting competitor's loved the size and the fact that they could shoot target's quickly while on the move all while keeping their other eye open. This little scope gives you an excellent field of view and outstanding light transmission. You would definitely need the P-Series AR Mount for this compact scope. I was telling a buddy who compete's in 3-gun competition's in NY about this scope and today he is trying to find one and get the FREE P-Series Mount.
Here's a pic from the Nikon website showing the scope and P-Series Mount.
