Simple, fast, effective the VMX-3T Magnifier will work with any vortex red dot but it is not recommended for use with the prism scopes. The push-button design of the VMX-3T engages and disengages the flip-mount, allowing the magnifier to lock in place. The result, 3x magnified or unmagnified views at will. Optics are fully multi-coated for optimal light transmission. Lightweight and tough; hard-coat-anodized machined-aluminum construction ensures durability. Internally nitrogen purged for reliable waterproof/fogproof performance. Ultimate magnified versatility for virtually any AR-height red dot sight.

Waterproof: O-ring seals prevent moisture, dust, and debris from getting inside the tube for reliable performance in all environments. Fogproof: Barrels are filled with nitrogen gas to inhibit internal fogging. Matte Black Finish: Hard-coat anodized for durability.
