Vortex Optics Defender-ST Micro Red Dot (3 MOA, DeltaPoint Pro Footprint)
The Vortex Defender-ST is a micro red dot built around a large aspherical lens, with a ShockShield polymer insert and Fast-Rack texturing on the front face for slide manipulation off hard surfaces. The single-piece 7075-aluminum body is designed to be waterproof, fogproof, and shockproof.
Features include motion activation with a 10-minute auto-shutoff, button lockout, and a top-load CR2032 battery system that allows battery changes without removing the optic from the slide.
