I have several Hawke scopes and they work 100%, good glass, magnum springer rated and good guarantee that they actually hold by. I once bought a used Hawke that had a problem and they replaced it for me with a new one. I have a 2-7 Airmax on my Gamo Magnum for many years now and it still works 100%.
The Vantage 4-12 with mill-dot reticle has fairly thick reticle lines but using it on my .50 muzzleloader the lines is OK. For a air rifle I like thinner lines. The Vantage 3-9 has thin lines so I don't know what is up with the 4-12. The Airmax 4-12 has thin lines as well.
