As Tonio and Dean says it is the updated version of Weaver V16. Nice scope and the Mil Dots look a lot nicer than the ones on the V24.
It is quite interesting how there are new scopes appearing on the market and a lot of them are re-badged Weavers i.e Lightstream = Weaver Tactical, above scope = Weaver V16, is there any more like it? I believe all these scopes originate at Light Optical Works in Japan, but is Weaver disappearing from the market?
