Just bought a Panamax 3-9x40 AO IR. Everything about it so far is better than the Hawke Airmax. Glass is clerarer, parallax ring is smoother, Mag adjustment is smoother too. Reticle isn't too thick or thin and is as good as the AMX. Pity you can't lock of eyebell adjustment.....not exactly loose but acan be accidentally moved. Not actually used it yet so can't comment on performance. Only reason went for IR version is that it has glass etched ret where as the non IR version doesn't
