@mealiejimmy would the pard work with a vortex viper scope with adjustable parallax?
Traditionally, Vortex scopes have not worked well with NV add-ons
From the reports of others, it appears that it is virtually impossible to get both the reticle and the image in focus at the same time.
It may be that the current Vortex Viper no longer suffers from this problem.
