The sight is Chinese, not Japanese manufacture and looks to be of dubious quality.
The reticles do distort geometrically (e.g., the ring reticle becomes an un-round loopy oval) if you allow them to approach the edge of the field of view. But the worst is I can't see how it can possible hold a stable zero, given how the optics simply sit out in the open suspended by the E&W adjustments from the mount. It seems that the slightest bump will disturb the zero.
But it looks so cool on the Shadow that I want desperately for it to work.
