Vortex 4-12x40 AO Crossfire II Riflescope (Dead-Hold BDC)

The  4-12x40 AO Crossfire II Riflescope (Dead-Hold BDC) from Vortex Optics is a cost-effective yet durable variable power riflescope. The 4-12x magnification is ideal for close to mid-range hunting and target practice. A nitrogen purged and o-ring sealed aluminium housing is built to perform in driving rain and extreme humidity. This model of the Crossfire II is configured with a Dead-Hold BDC reticle and low-profile capped windage/elevation turrets. The wide 40mm objective lens features enhanced light gathering ability that is well-suited for performance in low light conditions. An included sunshade prevents stray light that can degrade image quality from entering the field of view. A fast focus eyepiece, parallax error correction, and generous eye relief make the Crossfire II a full-featured scope for sportsmen.

Key Features:

Dead-Hold BDC Reticle

Customised compensating reticle subtensions minimise guesswork on holdover and wind drift corrections, ideal for shooting at ranges where calculating accurate bullet drop is essential.

Anti-Reflective Lens Coating

Fully multicoated optics and an additional anti-reflective coating on the objective and the ocular lenses ensure transmission of bright detail-rich images throughout the entire magnification range.

Rugged Construction

The one-piece aerospace aluminium housing is anodised for a durable non-reflective finish. Each optical element is held in place by machined locking rings that ensure perfect lens alignment even after intense recoil and rapid fire. Additionally, the interior is nitrogen purged and o-ring sealed, preventing driving rain and extreme humidity from fogging the optics.

Adjustable Objective

The focus ring on the objective bell enables parallax error correction and helps ensure accuracy at the far end of the magnification range.
