The Vortex Defender-ST Enclosed Solar Micro Red Dot is a next-generation pistol sight and micro red dot optic built for shooters who demand reliability and adaptability. Whether you mount it on a duty pistol, fit a revolver red dot for fast follow-ups, or top a compact shotgun or carbine, the Defender-ST’s enclosed housing protects the emitter from impact and debris so the sight picture stays clear in rain, mud, or dust. Its 3 MOA dot balances pinpoint accuracy and quick acquisition, while the 32 MOA circle option aids rapid target transitions and intuitive sighting in dynamic scenarios. As an enclosed solar red dot, it pairs long battery life with photovoltaic backup so you won’t be caught off guard by a dead cell.

SOLAR with Auto D-TEC pairs with a long-life CR2032 battery to deliver exceptional runtime, and motion activation with a 10-minute auto-shutoff saves power without compromising readiness. Multi-reticle flexibility and 12 brightness settings — including two night-vision compatible options — let you dial in an ideal sight for competition, duty, or everyday carry. Installation is simple with the DeltaPoint® Pro footprint and included Glock MOS adapter plate, and side-load battery access lets you replace the CR2032 without removing the optic or losing zero.

Optimized for the most-searched terms — “red dots,” “pistol sights,” “revolver red dots,” “micro red dot,” and “enclosed solar red dot” — the Defender-ST combines rugged construction, battery/solar redundancy, and performance features that keep you on target when it matters most.
