All the above units use pvs14 oculars, right? How much might it cost to have something that replaces the pvs14 hardware with a collimating prism/demagnifier? How much would something like this weigh? Is there a reason other than demand that something like this isn't in production? Some people might people might pay several thousand for this, considering it could turn your mk3 60m into something image-wise similar to a utc, just way heavier. Looking forward to expert thoughts.
