The Vortex Defender-ST Enclosed Solar Micro Green Dot (DFST-MGD3-E) is a rugged closed-emitter dot for pistols, shotguns and carbines. The fully enclosed 7075 aluminium housing protects the emitter from impact and the elements. It uses the DeltaPoint Pro footprint and includes a Glock MOS plate and a Picatinny mount.
The Enclosed Solar ST brings the sealed emitter, solar-assisted power and multi-reticle choice to the all-purpose ST platform. It gives a 3 MOA / 32 MOA green dot. Solar-assisted power with Auto D-TEC gives up to 150,000 hours of run time, or 35,000 hours on the side-load CR2032 battery alone. It weighs 46 g. Backed by the Vortex VIP lifetime warranty.

Frequently Asked Questions
Which Defender should I choose?
All Defenders share the same core features: motion activation, button lockout, ShockShield insert, Fast-Rack texturing and night-vision compatible settings. The differences are size, footprint and battery.
| Model | Footprint | Battery and run time | Weight | Dot options |
|---|---|---|---|---|
| Defender-CCW | Shield RMSc | CR1632, up to 9,500 hrs | 27 g | Red 3 / 6 MOA, Green 3 MOA |
| Defender-ST | DeltaPoint Pro | CR2032, up to 25,000 hrs | 42 g | Red 3 / 6 MOA, Green 3 MOA |
| Defender-XL | DeltaPoint Pro | CR2032, up to 25,000 hrs | 55 g | Red 2 / 5 / 8 MOA, Green 3 MOA |
| Defender-CCW Enclosed Solar | Shield RMSc | CR2032, 35,000 hrs (150,000 with solar) | 37 g | Multi-reticle, Red or Green |
| Defender-ST Enclosed Solar | DeltaPoint Pro | CR2032, 35,000 hrs (150,000 with solar) | 46 g | Multi-reticle, Red or Green |
The Tan, Blackout and OPMOD editions use the same optics as the matching standard model.
Will it fit my firearm?
This model uses the DeltaPoint Pro footprint. Many slides come cut for it, others need an adaptor plate. The Picatinny mount and Glock MOS plate in the box cover rails and Glock MOS slides. Contact us with your make and model and we will confirm what you need.
How long does the battery last?
Run time is up to 35,000 hours on the side-load CR2032 battery alone and up to 150,000 hours with the solar panel helping (3 MOA dot on setting 6, constant on). Auto D-TEC switches between solar and battery power automatically.
Red dot or green dot?
The optics are the same. Some shooters find a green dot easier to pick up in certain light or against certain backgrounds, others prefer red. Both are daylight bright and share the same brightness range.
How tough is it?
Vortex builds the Defender housing from 7075 aluminium. It is waterproof, fogproof and shockproof, with an O-ring sealed body and a fully enclosed emitter that stays protected from dust, debris and moisture.
What warranty does it have?
Vortex covers it with the unlimited, unconditional VIP lifetime warranty. In Australia, warranty service goes through Vortex distributor Extravision Australia.
