Vortex Defender-ST™ 3 MOA Green Dot Sight DFST-MGD3

The Vortex Defender-ST™ 3 MOA Green Dot Sight is built for shooters who demand speed, clarity, and resilience in every environment. Whether mounted on a handgun, shotgun, or offset on a carbine, this optic delivers rapid target acquisition and rugged dependability, making it equally suited for the range or duty use. Designed with precision engineering and built from durable materials, it’s an optic that doesn’t compromise under pressure.

The Defender-ST™ uses a bright 3 MOA green dot—the most visible color to the human eye—for quick and consistent target acquisition in any lighting or background. A large viewing window further enhances situational awareness, giving shooters the confidence to stay locked in without losing the field of view. Vortex’s ShockShield™ polymer insert protects the optic from daily abuse, while the Fast-Rack™ textured face allows shooters to rack their slide against any surface with speed and control.

With 10 daylight-bright settings and 2 night-vision-compatible modes, this optic adapts to any condition. The motion-activation system ensures it’s always ready when you are, powering on with movement and conserving battery life with a 10-minute auto shutoff. A convenient top-mount battery compartment allows for quick replacement without rezeroing—saving time and frustration.

The Defender-ST™ is built for hard use. Its single-piece chassis keeps it compact and lightweight, while the low-glare matte black anodized finish resists wear and reduces reflection. Waterproof, fogproof, and shockproof, this optic is engineered to withstand recoil, harsh weather, and the demands of real-world environments. With unlimited eye relief and parallax-free performance, it ensures rapid target acquisition without compromising accuracy.
