The new HX line are Optisan new entry level scopes and have been redesigned to have 25% larger field of view than most existing similar scopes in the market. They are built as a family of simple sturdy scope that holds most magnum center-fire calibers such as .270 Win .308, .30-06.
The lenses are multi coated and give the shooter a very clear view. The windage elevation adjustment comes with no-tool-required finger resettable zero feature. The parallax of the HX 4-12x40 AO is adjustable from 10 yards to infinity, which makes it perfect for airguns.
