8x28 R/T Roof Prism

The Viper 8x28 R/T tactical binocular has combat-specific features that can also meet the needs of hunters. With a tough, durable compact roof prism design and brilliant optics, the Viper R/T tactical binocular can be relied on in the worst conditions. The fully multi-coated optics and phase-corrected prisms deliver exceptional light transmission and brightness—even in low light. The Vortex R/T ranging reticle of the Viper R/T binocular accurately ranges targets and assists in calling shots. Waterproof, fogproof and shockproof.
