I've had a March 3-24x42, a March 5-40x56, a March HM 5-42x56, and now own a March shorty 1-10 as well as a March Genesis HM 4-40x52. Of all those only the Genesis has extremely nice glass and lacks odd optical distractions. The rest did not give me that WOW!! experience I was looking for.
On paper the March 4.5-28 HM is not so compromised optically whereas my 5-42 had some odd things about it optically. That's the March I'd try.
Though personally because of the lower power level of the mini I wouldn't spend the money for a March scope. Actually the Athlon DMR Helos G2 2-12x42 is pretty much perfect for it. You won't out shoot that .3 mil center dot outside of 25Y because at any distance inside 100Y that's about what your rifles precision is capable of in perfect conditions. Basically 1/4" at 25Y and 1/2" at 50Y, 3/4" at 75Y, and 1" at 100Y. See what I mean.
If not that ^ then the Helos G2 4-20.
