I recently purchased a "new in the box" ITAC DEFENSE Holographic sight. When I opened the box it had a SIGTAC holographic sight. Now, I'm no optics pro by no means, but it looks and functions like everything the paperwork says. It's made in the USA, NH, even the model number on the side is the same. The only noticable difference is the ITAC emblem thats on the box but not on the sight. It works great, but when I looked it up on the web I got some disturbing information about the sight being a china replica worth about $30. I paid $100.00 for this sight and just wondering if I got taken or is this the true manufacturer of SIGTAC holo sights. It was bought at a local reputable dealer. Let me clarify: the only difference is the sight on the box has a ITAC emblem on it and the actual sight has a SIGTAC logo in its place. Any help appreciated???
