Vortex Optics Viper HD 2-10x42 SFP Second Focal Plane Dead-Hold BDC MOA Riflescope - VPR-21001

• Ruggedly built on a 30mm tube, the Viper HD 2-10x42 features a 5x optical design and an illuminated second focal plane reticle.
• The Dead-Hold BDC uses a customized hash mark design that helps eliminate guesswork on holdover and windage corrections. Good for hunting at varying ranges, where estimating holdover is a concern.
• HD optical system is optimized with select glass elements to deliver exceptional resolution, cut chromatic aberration and provide outstanding color fidelity, edge-to-edge sharpness and light transmission.
• The fast-focus eyepiece easily adjusts the reticle focus. Capped windage and elevation protect the user from accidental adjustments.
• Ultra-hard, scratch resistant, Armortek coatings protect the exterior lenses of the scope. While shockproof, the Viper is also argon purged to ensure fogproof and waterproof performance in the field.

Specifications

What our Experts Think

• Highly versatile “do‑it‑all” magnification
  The 2–10× range is perfect for close to mid‑range shooting, offering a wide field of view at low power and enough zoom for precise shots at distance.
• HD optical clarity with strong low‑light performance
  The HD optical system and fully multi‑coated lenses deliver bright, sharp, glare‑free images, making it especially effective during dawn and dusk when visibility matters most.
• Dead‑Hold BDC reticle = simple, effective aiming
  The SFP illuminated Dead‑Hold BDC (MOA) reticle provides clean holdover references, helping eliminate guesswork for bullet drop and wind correction in real hunting scenarios.
• Lightweight and field-friendly design
  At ~20 oz, it’s easy to carry on long hunts while maintaining durability—ideal for mobile hunters and lightweight rifle builds.
• Reliable adjustments with capped turrets
  1/4 MOA click adjustments and capped turrets offer precise, repeatable dialing while preventing accidental changes in the field.
• Strong adjustment range for its class
  With ~135 MOA elevation and windage travel, it provides more than enough flexibility for extended-range shooting within its magnification limits.
• Rugged, all-weather construction
  Built with a single-piece aluminum tube, argon purging, and ArmorTek coatings, it’s waterproof, fogproof, and shock-resistant for harsh environments.
• SFP advantage: clean and easy sight picture
  The second focal plane design keeps the reticle consistent and uncluttered, though holdovers are accurate at a specific magnification setting.
