I really like my March HM 5-42x56!
Even with my crappy old eyes it's a beautiful sight picture below 30x. Superior IQ near the center of the FOV compared to my S&B 5-25's, a Kahles 5-25, and to a NF 7-35, the only other expensive scopes I've compared to with it. It's comparable to them from the middle of the FOV on out to the edges.
It seems guys with good eyes like the glass on 42x. 42x doesn't work well for my eyes though.
It has locking turrets and I like the locking levers more than the pull up/push down method used on other the brands locking turrets.
I also like the wide 10 mil turret spacing and medium feeling action. You won't over turn a click by accident and they are very distinct, no lash, and line up perfectly. My favorite of any I've felt including TT and ZCO.
Most guys love the FML-TR1 reticle. I don't even ask those who have looked through my scope if they do, instead that's the first thing they bring up. Seeing the reticle on 15x last weekend during the NRL22 match was easy and fast to pick up when transitioning to the next target.
40 mils of elevation travel but it's not advisable to "use" the max amount of travel in either direction due to IQ degrading, however it's there if you need it. Most scopes have IQ deterioration when travel is maxed out.
It focuses down to 8 yards on 42x, 6 yards on 10x. In case you want to shoot ants
or air rifle matches. On 15x I didn't find the parallax touchy, in other words it was a lot like my S&B PM2. On 42x it ranges better than any FT scope I've used. Only FT shooters understand what I'm meaning.
