I recently got a new DD M4A1 and will be using a Romeo 4T for my optic. I'm going to sight it in tomorrow and would like to know if 25 or 50 yards is the standard range?
Keep in mind you can only zero your equipment at whatever the max distance is of your shooting range. If your range only goes to 25 yds- then zero at 25 until you find a longer shooting range.
