Vortex Optics Red Dot StrikeFire II SF-BR-504

The Vortex StrikeFire II SF-BR-504 is a robust red dot sight that combines speed, reliability and ease of use in a single versatile optic. Thanks to its bright 4 MOA red dot, fully multi-coated lenses and a battery life of up to 80,000 hours, this red dot sight is suitable for airsoft, sport shooting and tactical applications where rapid target acquisition is essential.

The robust aluminium housing, water- and mist-proof construction and the mounting kit supplied mean the StrikeFire II is immediately ready for intensive use in a wide range of conditions.

Designed for speed and reliability

The StrikeFire II is designed for users who want to be able to locate targets quickly without compromising on accuracy. The 1x magnification and parallax-free design allow you to keep both eyes open whilst aiming, giving you the widest possible field of view and enabling you to react more quickly to moving targets.

The 4 MOA red dot is large enough to be easily visible in fast-moving situations, whilst at the same time offering sufficient precision for accurate shots at short to medium ranges.

A clear picture in all conditions

The fully multi-coated lenses maximise light transmission and ensure a clear, high-contrast image. This ensures that the sight picture remains clear, even in less favourable lighting conditions.

With ten brightness settings, you can easily adjust the intensity of the red dot to suit your surroundings. The lowest settings are also compatible with night-vision equipment, making the StrikeFire II suitable for professional or tactical use.

Robust construction for heavy-duty use

The housing is made from aircraft-grade aluminium and designed to withstand heavy loads and recoil with ease. Thanks to its hard-anodised finish, the red dot sight is resistant to wear and tear and has a matt finish that minimises unwanted reflections.

In addition, O-ring seals and an argon-filled design ensure that the StrikeFire II remains completely waterproof, dustproof and fog-free. This means you can rely on a clear reticle in virtually all weather conditions.

Long battery life and easy installation

The StrikeFire II is powered by a CR2 battery (included) and offers an impressive battery life of up to 80,000 hours on brightness setting 6. This means you’ll only need to replace the battery very rarely, even with regular use.

The included cantilever mount positions the red dot at a comfortable height for AR platforms and other replicas fitted with a Picatinny rail. A low-profile mount is also included, allowing you to easily adapt the sight to your setup.

Practical insights

Above all, a reliable red dot sight must be fast. The StrikeFire II has been recognised for years as one of the most popular models in the Vortex range, thanks to its combination of ease of use, excellent durability and long battery life. The large 4 MOA dot makes rapid target acquisition particularly easy, whilst the robust construction ensures that the optic can easily withstand intensive use on the airsoft field or at the shooting range.

Thanks to the high and low mounting options supplied, the StrikeFire II is also immediately compatible with a wide range of replicas and firearms.

Common mistakes

A common mistake is choosing the wrong mounting height. Use the cantilever mount if you want a higher line of sight – for example, on an AR platform – and the low mount if the red dot needs to be positioned as close as possible to the top of the rail.

You should also always check that the brightness setting is appropriate for the lighting conditions. If the dot is set too bright, it may make the reticle less sharp.
