Vortex Crossfire 4-12x40 BDC AO

The Vortex Crossfire 4-12x40 BDC AO offers sharper clarity, tougher construction, and brighter performance designed to meet the demands of modern hunting and precision shooting. This rifle scope is built to exceed the standards of similarly priced scopes, delivering longer eye relief, a fast focus eyepiece, fully multi-coated lenses, and precision-adjusted MOA turrets that reset to zero for rapid return to sighting-in accuracy. If you’re seeking a reliable optic that can keep up with field use, range days, and rugged backcountry conditions, the Crossfire 4-12x40 BDC AO stands out.

One of the standout advantages is the combination of durability and optical efficiency. The hard anodized, one-piece aircraft-grade aluminum tube is designed for strength and balance. It is nitrogen-purged and O-ring sealed, delivering true waterproof and fogproof performance in rain, dust, mud, and temperature swings. Whether glassing at dawn or chasing horizon light in the late afternoon, this rifle scope maintains a bright, high-contrast image that supports quick target acquisition and precise shot placement. In addition, the scope is shockproof, ensuring stable alignment after recoil and rough handling.

Optically, the Crossfire line features fully multi-coated lenses engineered to maximize light transmission and minimize reflections on every air-to-glass surface. That translates into brighter targets, crisper edges, and a more comfortable sight picture across low-light moments. The Dead-Hold BDC Reticle (MOA) with a customized hash mark design helps reduce guesswork on holdover and windage corrections, especially when shooting at varying ranges where holdover estimates can slow you down. For shooters who want repeatable, rapid adjustments, the turret system includes capped turrets for protection and resettable zero, allowing you to return to your zero quickly after sighting in.

Beyond optics, this rifle scope emphasizes field usability and practical value. The fast focus eyepiece enables rapid reticle sharpening on the fly, while the sunshade minimizes glare and sun reflections off the objective lens. The setup relies on a traditional 1-inch tube and a rugged one-piece tube that resist flex and maintain precise alignment under recoil. The aircraft-grade aluminum construction, paired with a hard anodized finish, delivers durability and a low-glare appearance that helps camouflage your position in the field. Together, these design choices translate into a versatile, dependable optic for hunting, target shooting, and long-range practice.

The Crossfire scope is designed to complement a wide array of rifle configurations, making it a flexible choice for upgrades or new builds. Whether you’re chasing game in timber, shooting at longer distances on open ranges, or competing in precision matches, the Crossfire provides a reliable optics solution with a robust feature set. Key performance parameters include a magnification range of 4-12x and a 40 mm objective, a practical eye relief of 3.9 to 4.4 inches, and a generous field of view that shifts from 24.7 feet at 4x to 8.4 feet at 12x per 100 yards. The 1-inch tube and one-piece design maximize durability while maintaining a compact footprint for maneuverability on the rifle.

Operationally, the scope offers 50 MOA of elevation and 50 MOA of windage adjustment, providing precise corrections across a wide range of distances and environmental conditions. Turret travel per rotation is 15 MOA, with 1/4 MOA graduation per click, delivering fine control for distance estimation and on-the-mly adjustments. The combination of a rugged body, machined locking rings to secure optical elements, and a precise optical axis makes this scope reliable through heavy recoil and rugged field use. Overall length is 13.6 inches and weight 19.2 ounces, delivering a balanced profile that complements a broad spectrum of hunting rifles without adding excessive bulk.
