One optic for every gun in your arsenal. It's no distant dream—the Vortex® Defender-ST^TM makes it a reality. It's the ultimate all-purpose red dot designed to fit and function flawlessly on everything—from EDC handguns to shotguns, paired up as the primary optic on your carbine, or piggybacked on your AR's LPVO.

Rugged and reliable? It’s a given. Large sight window? Absolutely. Motion-activation and a dot with adjustable brightness deliver superior target acquisition, adaptability in all lighting conditions, and faster follow-up shots. The 7075 aluminum housing features a polymer Shockshield^TM that absorbs impact to keep you in the action. And the Defender-ST is 100% waterproof, fogproof and shockproof to operate in any theater.

It fits the standard DeltaPoint Pro footprint, and includes both a Picatinny mount and Glock MOS adapter plate—so it's a perfect fit on a huge variety or platforms. If you want one optic that does it all—the Defender-ST is it.
