Vortex Diamondback 4-16x44 Tactical MOA Rifle Scope

Try not to spit out your coffee as you check the price of the Diamondback Tactical FFP after reading about its impressive performance and features. The first focal plane reticle, a feature ordinarily reserved for 4-figure-priced optics, allows shooters to use the information-packed EBR-2C reticles for ranging, holdovers or windage corrections on any magnification. Housed inside its durable, one-piece aluminum tube is a 4x optical system delivering excellent edge-to-edge clarity and sharp resolution. Exposed elevation and windage turrets are low profile enough to stay out of the way in packing situations, but offer the quickness, ease and precision of dialing accurate shots at distance. A side adjustable parallax gives shooters peace of mind by removing parallax error from the equation from 10 yards to infinity.

Optical Features:

• XD™ Lens Elements - Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.
• Fully Multi Coated Lenses - Anti-reflective coatings on all air-to-glass surfaces provide increased light transmission for greater clarity and low-light performance.
• First Focal Plane - Scale of reticle remains in proportion to the zoomed image. Constant subtensions allow accurate holdover and ranging at all magnifications.
• Glass-Etched Reticle - Allows for intricate reticle design. Protected between two layers of glass for optimum durability and reliability.

Construction Features:

• 30mm Tube Size - 30mm diameter provides maximized internal adjustment and strength.
• Nitrogen Gas Purged - Gas purged and o-ring sealed for fogproof and waterproof performance in all conditions.
• Aircraft-Grade Aluminum - Constructed from a solid block of aircraft-grade aluminum for strength and rigidity.
• Waterproof - O-ring seals prevent moisture, dust and debris from penetrating the riflescope for reliable performance in all environments.
• Fogproof - Nitrogen gas purging prevents internal fogging over a wide range of temperatures.
• Shockproof - Rugged construction withstands recoil and impact.
• Hard Anodized Finish - Highly durable low-glare matte finish helps camouflage the shooter's position.
• Precision-Glide Erector System - Uses premium components in the zoom lens mechanism to ensure smooth magnification changes under the harshest conditions.
• Exposed Tactical Turrets - The Diamondback Tactical scopes feature tactical windage and elevation turrets with Zero Reset making adjustments back to zero easy and quick.

Convenience Features:

• Fast Focus Eyepiece - Allows quick and easy reticle focusing.
• Magnification Rib - The raised rib on the magnification ring facilitates fast magnification changes in the heat of action.

Breakdown of MOA and MRAD:

• MOA (Minute of Angle)
  • What it is: MOA is a unit of angular measurement that is commonly used for adjusting rifle scopes and calculating shot placement. One MOA equals 1/60th of a degree.
  • How it works: At 100 yards, 1 MOA equals approximately 1.047 inches (usually rounded to 1 inch for simplicity).
  • Usage: Scopes with MOA adjustments typically allow you to "click" the scope turrets in small increments to move the point of impact. A typical adjustment might be ¼ MOA per click, meaning each click moves the point of impact about 0.25 inches at 100 yards.
  • Why it matters: MOA is useful for fine adjustments, particularly for precision shooting at long distances.
• MRAD (Milliradian or Mil)
  • What it is: MRAD (often just called "mil") is another unit of angular measurement. One mil is 1/1000th of a radian, and at 100 yards, 1 mil equals 3.6 inches.
  • How it works: Scopes with MRAD adjustments allow you to click in mil increments (often 0.1 mil per click), which corresponds to moving the point of impact by 0.36 inches at 100 yards.
  • Usage: Like MOA, MRAD is used for adjusting windage and elevation on scopes. It’s more common in military and long-range precision shooting.
  • Why it matters: MRAD is often preferred for its simpler math (1 mil at 100 yards is 3.6 inches, at 1000 yards, it’s 36 inches).
