From listening to
@koshkin , he has seen better performance at distance from the March 1-10 with an adjustable parallax compared to the Vortex G3 Razor 1-10 without one.
Sounds like the main difference comes down to end use and how much time you’ll actually be spending at 7-10 power and or distance.
Not saying its bad to have a non adjustable parallax on a 1-10 optic, just something to be aware of for the user.
