The Vortex Diamondback Tactical 4-16x44 FFP strikes a balance between affordability and professional-grade performance. Mounted on my Bushmaster Varminter using 30 mm rings and a 20 MOA mount, this scope excelled in both 100-yard target groups and 600-yard prairie dog shots.

Specs

Magnification: 4–16×
Objective Lens: 44 mm
Tube Diameter: 30 mm
Reticle: EBR-2C (FFP, MOA)
Adjustment: ¼ MOA per click
Weight: 23.1 oz
Parallax: Adjustable 20 yds – ∞

Pros

Crisp and repeatable turrets
FFP reticle ideal for holdovers
Excellent edge-to-edge clarity

Cons

Slightly heavy
Reticle lines may appear thin at low magnification

Glass Clarity & Reticle

Vortex’s XD glass shows superb color contrast. The EBR-2C reticle in the first focal plane ensures your subtensions remain consistent across magnifications — invaluable for long-range varmint work.

Eye Relief & Eye Box

At about 3.8 inches of eye relief, it’s generous for an AR-15 platform. The eye box is forgiving up to 12×, tightening slightly at 16×.

Fully shockproof, fogproof, and waterproof. Mine has survived dust, rain, and 500 rounds of .223 without losing zero.

Elevation & Windage

Clicks are distinct and tactile. The turret tracking passed my box-test within ¼ MOA precision.

Magnification & Parallax

Side-adjustable parallax is smooth. The 4–16× range covers everything from 100-yard coyotes to 700-yard steel.

Mounting & Accessories

I used a Vortex cantilever 20 MOA mount — perfect fit and maintained bore alignment.

Personal Experience

I achieved a 0.7 MOA 5-shot group at 200 yards. For the price, the consistency amazed me. Many Reddit users echo this, praising its “zero-drift reliability.”

This is the perfect all-rounder for the Bushmaster Varminter — ideal for those who demand FFP precision without premium pricing. ​

How to Choose the Right Scope for the Bushmaster Varminter

Magnification Range: For varmint hunting, 3-9× works for 100–300 yards, while 4-16× or 6-24× excels at 400+ yards.
Reticle Type: Choose BDC or MOA reticles for drop estimation. FFP reticles maintain subtension accuracy across magnifications.
Objective Lens Size: 40–50 mm offers a good balance between light transmission and weight.
Turret Precision: Look for crisp ¼ MOA or 0.1 MIL clicks. Zero-stop systems are valuable for long-range dialing.
Eye Relief: Ensure at least 3.5 inches for AR-15 style platforms.
Build Quality: Go for nitrogen-purged, aircraft-grade aluminum tubes to handle recoil and weather.
Weight & Balance: Keep it under 30 oz for field use to maintain rifle agility.

FAQs

1. What magnification is ideal for the Bushmaster Varminter? A 4–16× or 6–24× scope is ideal for long-range varmint shooting, while 3–9× suits closer predator hunts.
2. Should I choose FFP or SFP for my Bushmaster Varminter? If you shoot across varying distances, FFP is superior for consistent holdovers. SFP is better for lightweight simplicity.
3. What’s the best budget scope option? The Leupold VX-Freedom 3-9x40 or Burris Fullfield IV 3-12x42 delivers outstanding value without sacrificing clarity.
4. Can these scopes handle .223 recoil? Absolutely — every scope listed here withstands the mild recoil of a Bushmaster Varminter with ease.

6. Are illuminated reticles worth it? For early morning or dusk hunts, illumination helps tremendously with fast target acquisition.
7. What rings or mounts should I use? Use 30 mm or 1 inch rings (depending on tube size) with a cantilever 20 MOA base for optimal eye relief on the Varminter platform.

Conclusion

After months of testing, my top recommendation for the best scope for Bushmaster Varminter is the Vortex Diamondback Tactical 4-16x44 FFP.
