I put classic Adjustable Objective Leupolds on mine, simple cross hairs. 3-9x40 on HW30s, 6.5-20x40 on HW95.
Neither are current models but were widely sold and available as old stock or used. Be sure to get the Adjustable Objective (Adjustable Parallax) models that go down to 10 yards.
High build quality, great warranty, clear glass in one-inch tubes, lightweight and springer safe. No silly Chinese logos or tactikewl decorations.
Expensive but not out of sight.
If Leupold wasn't making so much money from the military LEO contracts and FUDD types then they ought to redesign a series of modern airgun scopes with side focus, larger tubes and modern reticles.
But I rather like the classic old-school scope with classic rifles.
