They dont need to be adjusted if you match the reticle to your gun.
While your farting around spinning turrets, Im sending lead downrange. plus I never have to worry about the turret getting spun, or not returned to its zero setting.
Granted a BR may not be as accurate as turrets, but how much accuracy do you need? I know I can shot 12" steel plates in 100yard increments at the gun club with ease, by just using the reticle. Thats good enough for me.
