That reticule struggles to sell, as it s poor at delivering the kind of precision now demanded.
That design is fast, but far too easy to get elevation out as its far too easy to "push into" the target. Really a close range, point blank, hunting reticule. They were made that way because when crosshairs were "wire", actually physical rather than etched, then they were beefy enough to be robust. One reason the military used to like them too.

They do come up on older scopes, quite good quality ones too. Most sellers should bite your hand off just to move one on.
