Master airgunners collaborated to create the Aztec Emerald line of scopes. Each pitching in what they felt was desired most, and would facilitate a great shooting experience. The result was one of the best suited scopes for airgun enthusiasts. It brings many of the features/accessories left out by other manufactures, at least in a single package. It comes with a removable extra large parallax wheel, so you can attain those perfect settings of clarity. As well as a sunshade to keep the bright sun from over exposing the incredibly clear glass. They moved away from large clunky tactical turrets, and went with a more streamline design keeping things nice and neat while still lockable. An immense amount of thought went behind the reticle design by top hunters. Therefore this design produces accurate shot placement and range estimation. The Aztec Emerald also excels in target shooting, and even won 1st place at the 2017 Extreme Benchrest contest! Both focal planes are now available. If you prefer FFP for hunting or any other quick shot acquisition scenarios, take a peek at the Aztec Emerald FFP. Since the FFP is geared more towards airgun hunting they have also added an illuminated reticle which is not found on the SFP edition.
