Product Info for VORTEX 4 MOA StrikeFire II Red Dot Sight (SF-BR-503)

When situations demand split-second target acquisition and maximum field of view, mount up the StrikeFire II and shoot - both eyes open.

Feature-rich, versatile and reliable, the StrikeFire II is a great choice for shooters who want a quality red dot sight, but don't want to break the bank.

Features sleek rear-facing controls for power on/off and easy adjustment of ten dot intensity levels - lowest two settings are night-vision compatible.

Automatically returns to the last dot intensity used when powered up. The 30mm aluminum alloy chassis provides extra-high recoil rating and is waterproof and fogproof. Strike fast!


The lower 1/3 co-witness cantilever mount model is ideal for platforms, positioning the optic bore center 40 mm above the base surface.


Fully Multi-Coated: Multiple anti-reflective coatings on all air-to-glass surfaces increase light transmission.

Bright Red Dot: Display is highly visible in daylight.

Brightness Settings: 10 Levels

Parallax Free: All red dot and holographic sights will exhibit some small amount of parallax. Matching current industry practice, this small amount would be considered "parallax free" and will make a negligible difference in the StrikeFire II's performance.


Single-Piece Chassis: Maximizes strength and waterproofness. Compact and lightweight.

Waterproof: O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments.

Fogproof: Nitrogen gas purging delivers fogproof, waterproof performance.

Shockproof: Rugged construction withstands recoil and impact.

Hard Anodized Finish: Highly durable low-glare matte finish.

Operating Temperature: Rated from -22 degrees to +140 degrees Fahrenheit.


Cantilever Ring Mount: Puts the optic bore center 40 mm above the base, providing lower 1/3 co-witness with iron sights on flat top rifles.

Unlimited Eye Relief: Non-critical eye relief for rapid target acquisition.

Adjustable Dot Intensity: Provides ten variable illumination settings - the lowest two settings are night-vision compatible.

Battery Life: 12-hour auto-shutdown feature maximizes battery life. Typical battery life is 400 hours at maximum brightness and 7,000 hours at minimum brightness setting.
