Vortex Optics Diamondback 4-12x40 SFP Riflescope (MOA) Reticle, 1 inch Tube with Wearable4U Bundle - VMR-1

Vortex Optics Diamondback 4-12x40 SFP Riflescope  (MOA) Reticle, 1 inch Tube with Wearable4U Bundle - VMR-1

Exposed turrets built for dialing elevation and windage allow wind drift compensation at extended ranges. When we say precise - we mean it. These turrets track better than any Bloodhound and reliably return to zero every time. A zero-reset feature lets you re-index the zero reference marks on both turrets after sight in, while fiber optic rotation indicators integrated into the turrets provide a visual cue of your turret’s position.

  Delivers clear optics, solid tracking, and durable construction at an entry-level price—making it one of the best-value scopes for beginners and casual shooters
• Versatile 4–12x magnification for real-world use
  Ideal for short to mid-range shooting (100–600 yards), offering enough zoom for precision without sacrificing usability
• VMR-1 MOA reticle = simple but effective
  Provides useful hash marks for holdovers and wind correction while maintaining a clean, uncluttered sight picture—great for learning MOA shooting
• Second Focal Plane (SFP) for clarity and ease
  Reticle stays consistent in size, making it easier to see and use—best optimized for accuracy at higher magnification
• Reliable turret system for dialing adjustments
  Exposed turrets with 1/4 MOA clicks and ~70 MOA travel provide dependable tracking and repeatability for dialing elevation and windage
• Surprisingly good optical quality for the class
  XD glass and fully multi-coated lenses deliver sharp images, good contrast, and solid low-light performance for its price range
• Rugged, field-ready construction
  Built from aircraft-grade aluminum and nitrogen-purged for waterproof, fogproof, and shockproof performance
• Lightweight and easy to mount (1-inch tube)
  At ~16–17 oz, it keeps rifles balanced and works with widely available mounting systems

Maintenance Tips

• Clean lenses gently: Use a microfiber cloth or lens brush to protect multi-coated optics and maintain sharp image quality.
• Check mounting hardware: Ensure rings and base are properly torqued to maintain zero under recoil.
• Inspect turrets regularly: Confirm smooth elevation and windage adjustments for consistent accuracy.
• Keep lenses covered: Use lens caps to prevent dust, scratches, and environmental damage.
• Avoid harsh chemicals: Only use optics-safe cleaning solutions to preserve coatings.
• Store in a cool, dry place: Supports long-term durability and internal seal integrity.
• Verify zero periodically: Especially after transport or extended use.
