The Vortex Diamondback 3-9x40 is a series of popular and versatile riflescopes known for their excellent price-to-performance ratio, making them a go-to choice for hunters and shooters . However, it's important to note that there are two distinct variants under this name: the standard Diamondback hunting scope and the Diamondback Tactical . The standard model is widely available, while the Tactical version has been discontinued by the manufacturer .

Here is a description of the key features, combining information for both variants.

Key Features and Optical Performance

The Diamondback 3-9x40 is built on a 1-inch tube and constructed from a single piece of aircraft-grade aluminum, ensuring it is shockproof, durable, and capable of withstanding significant recoil . It is also nitrogen or argon gas purged and O-ring sealed, making it both waterproof and fogproof in all weather conditions .

Optically, it features a fully multi-coated lens system (referred to as XD™ Optical System and XR™ Lens Coatings by Vortex). This premium anti-reflective coating on all air-to-glass surfaces provides exceptional light transmission, resulting in bright, clear, and high-contrast images, especially important during low-light conditions like dawn and dusk . The scope has a 40mm objective lens and offers a magnification range of 3x to 9x, making it ideal for a wide variety of hunting scenarios and general shooting .
