Vortex Defender-ST Micro Red Dot Sight – 3 MOA

The Vortex Defender-ST Micro Red Dot Sight combines rugged construction, a crisp 3 MOA bright red dot, and versatile mounting compatibility in a compact optic designed for a wide range of applications. Available in Black (DFST-MRD3) and Tan (DFST-MRD3-T), the Vortex Defender-ST Micro Red Dot Sight delivers the durability and adaptability expected from Vortex Optics.
