How far out is a 1-4 power scope effective and if I got a 3-9 how much would the 0-50m range and speed be impaired.
I use a 1-4 MTAC on my competition AR and I can hold 8" 5 shot groups easily at 600 yards. When I put a 10x optic on the same rifle, my groups are about 5" at 600 yards. At 300 yards, I am right at 3" with the 4x and always under 2" with the 10x.

When I leave 1x (for 1.5 or 2x) in the 1 yard to 25 yard range, my target transitions slow by about 25% in daylight and about 40% in the dark.
