Vortex Defender ST FDE 3 MOA Red Dot, DPP Footprint, DFST-MRD3-T
The Defender-ST™ in Matte Tan Anodized finish is the all-purpose red dot built for duty, defense, and demanding range days.
With a DeltaPoint Pro footprint, the Defender-ST expands compatibility across popular platforms, giving you flexibility in setup without sacrificing reliability. Its large sight window and aspherical lens provide a distortion-free view, while the daylight-bright 3 MOA red dot makes target acquisition fast and precise in any lighting condition.
Why the Defender-ST™ Stands Out
- Versatile Mounting – Perfect for pistols, shotguns, or as an offset red dot on a carbine.
- Built for Abuse – ShockShield™ polymer insert and rugged single-piece chassis shrug off daily impacts, recoil, and duty use.
- Always Ready – Motion activation with 10-minute auto shutoff ensures the sight is ready when you are while preserving an impressive 25,000-hour battery life.
- User-Friendly Design – Top-loading CR2032 battery, button lockout, and Fast-Rack™ textured front face for racking off any surface.
- Mission-Ready Finish – Matte TAN anodization reduces glare, resists corrosion, and blends seamlessly into duty or concealment environments.
