How I Tested the Burris Fullfield IV 4.5-14x42mm
The scope was mounted on a Tikka T3x in 6.5 Creedmoor using Burris Signature Zee rings. All accuracy testing was conducted using Hornady 143gr ELD-X ammunition to ensure consistency.
Testing included extensive range work with 25 three-shot groups at varying distances from 100 to 500 yards. Tracking precision was verified using a 10-MOA box test repeated five times to assess repeatability and return-to-zero capability.
Field evaluation encompassed 24 days of hunting across three seasons, including high-altitude elk hunting and prairie dog shooting. The scope faced temperatures ranging from 12°F to 95°F and underwent testing in rain, snow, and dusty conditions.
Durability assessment included over 300 rounds fired, multiple pack-ins on horseback, and regular transport in varying weather conditions. Special attention was paid to thermal stability and point-of-impact shift during temperature changes.

Optical Performance & Reticle
The Fullfield IV demonstrates impressive optical clarity for its price point. The glass quality shows marked improvement over previous generations, with excellent center-field sharpness and minimal edge distortion even at maximum magnification. The Ballistic E3 reticle proved particularly effective for holdovers, though the illumination could be brighter in full daylight.
Light transmission impressed during dawn and dusk hunting sessions, with the scope maintaining target discrimination well into low-light conditions. The Hi-Lume multicoating system effectively managed glare, though some chromatic aberration was noticeable at higher magnifications.
Turret System & Tracking
The Zero Click-Stop turrets delivered consistent, positive clicks with good tactile feedback. Each adjustment tracked true to the 1/4 MOA specification, with minimal deviation observed during extensive box testing. The return-to-zero feature functioned flawlessly throughout the evaluation period.
Long-range testing showed repeatable elevation adjustments out to 500 yards, though wind adjustments exhibited slight inconsistencies beyond 400 yards. The zero-reset function proved reliable and user-friendly, a notable improvement over previous Fullfield models.
Magnification Range & Parallax
The 4.5-14x magnification range offers versatility for both close-quarter woodland hunting and longer-range prairie shooting. Image quality remained consistent through most of the zoom range, though some resolution loss was evident above 12x power.
The side parallax adjustment, marked from 50 yards to infinity, provided precise focus control. Minimal parallax error was observed between 100-400 yards, though careful adjustment was needed for precise shots at closer ranges.
Eye Relief & Eye Box
The generous eye relief range of 3.5-4.2 inches proved comfortable across various shooting positions. The eye box showed good forgiveness at lower magnifications, though it became notably tighter above 10x power.
Quick target acquisition was consistently achievable in field conditions, even from unconventional positions. The scope performed well during rapid follow-up shots on prairie dogs, indicating good practical usability.
Build Quality
Construction quality exceeded expectations for the price point. The scope maintained zero through multiple drop tests and showed no internal fogging during severe weather exposure. The anodized finish proved resistant to scratches and wear during field use.
Nitrogen purging and double internal spring-tension system demonstrated excellent reliability. The scope endured significant temperature fluctuations without any point-of-impact shift or internal condensation issues.
Mounting & Accessories
For optimal performance, I recommend:
- Burris Signature Zee rings (medium height)
- Professional-grade bubble level
- Quality torque wrench
- Butler Creek flip-up caps

The competitive landscape in this price range offers several compelling options:
The Vortex Crossfire II 4-16×44 provides slightly more magnification but falls short in optical clarity compared to the Burris. While the Crossfire II offers excellent warranty coverage and slightly better low-light performance due to its 44mm objective, its tracking precision and edge clarity don’t quite match the Fullfield IV. The Vortex typically retails for about 15% less than the Burris, making it an attractive alternative for budget-conscious buyers willing to accept some optical compromises.
The Leupold VX-Freedom 4-12×40 stands as a strong competitor, featuring Leupold’s renowned build quality and excellent optical clarity. Its edge-to-edge sharpness rivals the Burris, though it offers less magnification range. The VX-Freedom’s lighter weight and more compact design appeal to mountain hunters, but its turret system lacks the tactical feel and precise adjustments of the Fullfield IV. Priced similarly to the Burris, choosing between these two often comes down to personal preference for features versus compactness.
The Athlon Argos BTR 6-24×50 offers higher magnification and a larger objective lens at a competitive price point. While it provides good value with features like illuminated reticle and parallax adjustment, its optical clarity and mechanical precision don’t quite match the Fullfield IV’s standards. The Argos BTR typically runs about 10% less than the Burris and might appeal to budget-conscious buyers looking for higher magnification, but the Fullfield IV’s superior glass quality and more reliable tracking make it a better choice for serious hunters prioritizing optical performance in the field.
