I have the Accupoint 3-9 with Mil Dot crosshairs and green dot on a T3 in .243. I use it on called coyotes and so far it has been excellent, quick to get on target, clear and bright. I keep the power set at 4x and have killed coyotes from 40 to 200 yds. I also have a 1- 4 on a Bushmaster AR with the red triangle but prefer the green dot.
