Ran one for awhile, good scope if you can pick one up for less than $1500, at retail there are much better options. The M5A turret is HUGE and it takes alot of getting used to pushing the button on top to dial. The Mark 6 3-18 with the C2 turret is probably a better option for hunting, much more compact with a nice low profile zero lock turret. You can find them used for $1500-1600.
I have two,excellent rifle scope M5.
Mk4 series ERT was the ancestor for such series as Mk6 and Mk8 (if not mistaken).
NO Illunination? - YES only ERT.
I really like the Leupold ERT 6.5-20. The TMR reticle has good thickness over the full mag range. The turrets have good feel, spacing and clicks. The glass is good and clear. And it tracks repeatedly. Used ones show up in the post exchange frequently in the 1k range. It’s tempting not to pic up another one.
This. I run two now.
Much better image clarity and no color fringing like the Mk6.
I also own a Mk8 but prefer the Mk4 for size, weigh, simplicity and image clarity.
