I doesn't quite meet your requirements but the SFP Vector Veyron 3-12x44 is pretty compact and doesn't have an overly busy reticle. You can usually find them on sale at DVOR for $120 or so.
If you look closely at the West Hunter, USO and Veyron 3-12 you can tell that all three are pretty much the same scope. I’m pretty sure they’re all made with the same tube at the same factory with just a few different specs.
Vector makes a nice little scope. Have one on my Leshiy. Also UTG is worth checking. Had one of those on my Leshiy for some time as well. Great scope and was only around $160 I think. Still have it on a HW97.
Got a M3 compact coming. Looking a decent compact scope for it to keep it light. Anybody got any experience on them. Prefer something under the $4-500 range.
