One optic for every gun in your arsenal. It's no distant dream-the Vortex Defender-ST 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 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.
