sorry should have said do i have to re zero when i want to use a gun lamp, obviously i don t have the lamp attached all the time ,so with the extra wieght will it effect the point of impact?
In a word , NO . Although things can look very different through a scope at night , especially using a red filter . It may take a while to get used to judging distances , as always , get to `know` your set up , and it`ll be fine .
