Dead-Hold BDC (MOA) Reticle | 1 inch Tube
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 fogproof 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.

| Tube Size | 1 inch diameter tube offers a versatile blend of adjustment, size and weight for a wide variety of shooting applications. |
| Single-Piece Tube | Maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and waterproofness. |
| Aircraft-Grade Aluminum | Constructed from a solid block of aircraft-grade aluminum for strength and rigidity. |
| Waterproof | O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments. |
| Fogproof | Argon gas purging prevents internal fogging over a wide range of temperatures. |
| Shockproof | Rugged construction withstands recoil and impact. |
| Hard Anodized Finish | Highly durable hard-coat anodization provides a low-glare matte surface and helps camouflage the shooter's position. |
| Capped Reset Turrets | Allow quick re-indexing of the turret (no tool needed) to zero after sighting in the riflescope. Caps provide external protection for turret. |
| Precision-Glide Erector System | This system ensures the components in the zoom lens mechanism glide smoothly and cleanly through all magnification ranges. |
| Fast Focus Eyepiece | Allows quick and easy reticle focusing |
