Aforementioned Leupold, kahles, steiner (military line only; the “T” series are budget and look/feel like it), Minox, TT, ZComp (5-27) or SB (5-25, 3-27).
I would suggest trying to get behind a few of these before buying, perhaps at a local match or shooting range. Glass is subjective and you may like one or two more than the others but any/all of the above are alpha. Also consider what reticle designs you prefer relative to what’s available...
Either way, you won’t be disappointed.
