Are you talking about the integrated laser rangefinders? Or just subtension marks (or similar) that can be used to calculate range?
I think he is referring to a measuring reticle
I don't think Nikon maker anything with a integral laser
I wasn't certain if he was thinking of these:
Laser IRT - Riflescopes | Nikon Hunting
Scopes - rifle scopes, handgun scopes, hunting scopes by Burris Optics
I've been looking alot at products Burris and Nikon have in scopes. These two manufacturers have range finding scopes built for an AR platform. I'm curious if anyone has one of these and can provide some imput. Probably would not buy a Burris but it does have some nice features.
thank you!
