I really like the 12X. Have it on a couple of rifles.

Seems to be a great balance of fov, magnification, brightness, and overall size for most of my LR shooting. Then it has 43 mils erector travel, that's great for LR.

I was using fixed 16X before, but prefer the SWFA 12X by a huge margin.

Still have a SWFA 16X on one of the 308s, but look to replace it eventually.
