Vortex VMX-3T 3x Sight Magnifier

Push your red dot further with the Vortex VMX-3T Reflex Sight Magnifier — a purpose-built 3x optical booster designed to work seamlessly behind any unmagnified red dot sight. Mounting directly behind your primary optic, the VMX-3T extends your effective range without disrupting your existing zero or iron sight alignment. Whether you're running absolute co-witness or lower 1/3, this magnifier plays well with standard AR-style iron sights right out of the box.

Precision Alignment, Zero Compromise

The VMX-3T's dual-axis centering screws let you dial in windage and elevation correction independently of your primary optic — so aligning the magnifier never means re-zeroing your red dot. When the extra reach isn't needed, the integrated quick-release flip mount lets you swing the magnifier out of the way in a single motion, keeping your primary optic front and center.

Built for the Long Haul

Optical performance stays sharp through the fully multicoated lens system, which maximizes light transmission from your primary optic even in low-visibility conditions. The machined aluminum housing wears a corrosion-resistant anodized hard coat and is nitrogen-filled for reliable fogproof, waterproof operation. A generous 3.25-inch eye relief and focusable objective lens round out a package that's backed by a 1-Year Warranty.
