I have a Millett DMS 1x4 that I ran on my M14s before I decided I wanted to push it out a lil further and put a Leupy Mark IV 3.5-10 on her. No problems making hits on silhouettes out to 300ms with it at 4x, especially with a 200m zero, just learn your holdovers. Held up fine to the recoil of the M14 as well, still have it sitting in my closet, come to think of it, with some ARMS22 low rings on, perfect to get as low as you can on a ARMS18 mount. I'd part with it if you were interested, been sitting in my closet for a couple years now, haha
