First, the solid one-piece aircraft-grade aluminium alloy construction makes the Vortex Diamondback 4-12x40 riflescope virtually indestructible and highly resistant to magnum recoil. Argon purging puts waterproof and fog proof performance on the agenda, and advanced fully multi-coated optics raise an eyebrow when crystal clear, tack-sharp images appear in the crosshairs. Look for all this and more in a riflescope you'd expect to cost quite a bit more-but doesn't. We can live with that.
