I wouldnt buy a variable in that range myself, I tried it years ago and never saw any use for a 1 or 2 power. It actually makes the target look farther away to me. I know the argument for these powers is sight aquisition, but I dont have any trouble aquiring a moving target at 4x. Thats probably what I would put on that rifle. M-8 in straight 4x. Have fun with it.
