VORTEX Red Dot StrikeFire II LED Upgrade

VORTEX Red Dot StrikeFire II LED Upgrade is built for split-second target acquisition with a generous field of view and simple controls. The 30 mm tube expands your sight picture and works with common 30 mm rings at a wide range of heights. A crisp 4 MOA dot—available in red or user-selectable red/green depending on model—stays easy to pick up at true 1× for fast, both-eyes-open shooting.

Speed, versatility and value

From AR-15s to shotguns, the StrikeFire II shines as a lower 1/3 co-witness solution using the included cantilever mount, positioning optic centerline about 40 mm above the rail. Unlimited eye relief and a parallax-free design help you run a natural head position without chasing the dot.

Controls and adjustments

Dial in 1/2-MOA clicks with 25 MOA per rotation, and use the broad 100 MOA elevation and 100 MOA windage travel to zero on most platforms. A CR2 battery powers the dot for extended runtime, and flip-cap covers protect the lenses between stages or during transport.

Rugged construction and optics

The one-piece housing is waterproof, fogproof, and shockproof for real-world reliability. Fully multi-coated lenses deliver a bright, clean image that helps you confirm targets quickly at close and mid-range.

Visibility and brightness

Multiple daylight settings—and low settings that are night-vision compatible on certain versions—let you match the dot to conditions without blooming, preserving precision and situational awareness.

Setup tips

Mount to a Picatinny rail with the included cantilever to achieve lower-third co-witness on flat-top ARs. Zero at your preferred distance using 1/2-MOA clicks, confirm at a second range, and run the lowest usable brightness to preserve low-light vision and a sharp dot.

AR-15 carbines, PCCs, shotguns, home-defense builds, competition and training—the VORTEX Red Dot StrikeFire II LED Upgrade brings dependable speed and a big sight picture at a friendly price.
