Simple, fast, effective. 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.\r\nThe VMX-3T Magnifier will work with any of our red dots but it is not recommended for use with the prism scopes.\r\n\r\nFeatures\r\n\r\nMulti-Height Mounting System – Allows for lower 1/3 or absolute co-witness mounting heights and is ideal for shooters who want to increase the effective range of their red dot sight.\r\nFully Multi-Coated – Proprietary coatings increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.\r\nWaterproof – O-ring seals prevent moisture, dust and debris from penetrating the binocular for reliable performance in all environments.\r\nFogproof – Nitrogen gas purging prevents internal fogging over a wide range of temperatures.\r\n\r\n\r\nSpecifications\r\n\r\nEye Relief: 2.2\
