Sight is good - sight mount is garbage - Nikon P-Tactical Superdot 2 MOA Red Dot Sight

Love the clear lens (no tint) and very sharp dot. However, the Picatinny mount that came with the sight is garbage. Mount is loose (banging around) with screw fully tightened. Why can't a company such as Nikon produce something as simple as a decent mount? If I want to add a QD mount, then that should be an option - but having to buy something else just so I can mount the sight is unacceptable.
