Precision Optics for Target and Hunting

The Vortex Crossfire II 4-12×50 AO delivers serious performance at a sensible price. The 4-12x magnification range covers everything from close hunting shots to precise target work, while the light-gathering 50mm objective keeps the image bright when the sun is low. A fast-focus eyepiece lets you get the reticle sharp in seconds.

Dead-Hold BDC Reticle

The Dead-Hold BDC (MOA) reticle takes the guesswork out of holdover and windage. Calibrated reference points let you compensate for bullet drop at distance without touching the turrets, so you stay on target as ranges change. Finger-adjustable, zero-reset turrets make sighting in quick and repeatable.

Built to Take a Beating

Machined from a single piece of aircraft-grade aluminium with a hard anodised matte black finish, the Crossfire II shrugs off recoil and knocks. It is nitrogen purged and O-ring sealed, giving you fogproof and waterproof reliability whatever the British weather throws at your session. The adjustable objective dials out parallax for a crisp, accurate sight picture at every distance.

Lifetime Peace of Mind

Every Crossfire II is covered by the Vortex VIP warranty: unlimited, unconditional and lifetime. If it is ever damaged or defective, Vortex will repair or replace it, no receipt needed. Explore the rest of our outdoor shooting range to complete your setup. Mounts are sold separately, so ask our team for the right 1 inch rings for your rifle.

Frequently asked questions

What is the Dead-Hold BDC reticle used for?

The Dead-Hold BDC reticle gives you calibrated holdover points below the centre crosshair and windage marks either side, so you can compensate for bullet drop and wind at longer ranges without dialling the turrets. It suits shooters who engage targets at varied distances and want a fast aiming reference.

Does the adjustable objective help with air rifle shooting?

Yes. The adjustable objective (AO) lets you remove parallax error and sharpen focus at the shorter ranges typical of air rifle work, as well as out to distance. That precise focus matters for the tight groups sub-12 ft/lb air rifle shooters chase.

Are scope mounts included?

No, mounts are sold separately. This scope uses a 1 inch tube, so you will need 1 inch rings or a one-piece mount matched to your rail (Weaver, Picatinny or 11mm dovetail). Our team can advise on the right height and base for your rifle.

Is the Vortex VIP warranty valid in the UK?

Yes. The VIP warranty is unlimited, unconditional and lifetime, fully transferable with no receipt required. Vortex will repair or replace the scope if it is ever damaged or defective, though it does not cover loss, theft or deliberate damage.

What is the difference between the 4-12x50 and the 4-12x40?

Both share the same magnification and Dead-Hold BDC reticle. The 50mm objective on this model gathers more light for a brighter image in dawn, dusk and low-light conditions, at the cost of slightly more weight and a taller mounting height than the 40mm version.
