I have one on a 20" barreled .308 that I use a lot for deer hunting.

It does not appear oversized on the small rifle, has plenty field of view for the typical close-in shots, and the top power is enough for shooting the occasional long shot.

I also leave it on 2X, especially if in the woods.

I am able to shoot during legal hours. The day after Thanksgiving, I had to wait on the clock to shoot a deer that I could see plainly through the scope.
