The Diamondback loaded with features. First, the solid one-piece aircraft-grade aluminum alloy construction makes the Diamondback 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.
