The Burris Fullfield 3-12x42mm #201533 combines a versatile 3-12x magnification range with an illuminated Wind Ret reticle, side-focus parallax adjustment and advanced exposed turrets. This configuration is designed for hunters and shooters who want the compact versatility of a 42mm objective while also having the adjustment features needed for more precise shooting at extended distances.
At 3x, the scope provides a broad field of view for quickly locating and acquiring targets. Increasing magnification to 12x provides additional target detail for longer shots. High-performance glass and multi-coated lenses help maintain a bright, clear image across the magnification range.
The Wind Ret-Illuminated reticle is designed for shooters who want to dial elevation while using the reticle's symmetrical MOA wind hold marks to compensate for changing wind conditions. An illuminated center cross helps draw the eye toward the aiming point and improves reticle visibility in low-light conditions.
Because the reticle is located in the rear focal plane, its appearance remains consistent as magnification is changed. This makes the reticle quick to acquire and easy to use throughout the 3-12x magnification range.
The 3-12x magnification range gives the Fullfield a useful combination of field of view and target detail. At 3x, the scope provides a 36-foot field of view at 100 yards, making it well suited to closer and moderate-range hunting. At 12x, the field of view narrows to 9.25 feet, providing significantly more detail for longer shots.
Burris's improved 4x zoom system allows the Fullfield to provide this broad magnification range while maintaining a compact 11.1-inch overall length.
The 42mm objective lens provides a practical balance between light-gathering capability and overall scope size. It is large enough to support bright images in changing light while keeping the Fullfield more compact than scopes using larger 50mm or 56mm objectives.
Burris uses high-performance glass and multi-coated lenses to improve brightness and clarity while reducing glare. The scope provides an exit pupil ranging from 10.5mm at 3x to 3.5mm at 12x.
One of the key differences between the 201533 and the other Fullfield 3-12x42mm configurations is its adjustable parallax system. The 201533 uses side-focus parallax adjustment from 25 yards to infinity.
Adjustable parallax is particularly useful when shooting at higher magnification, where small changes in eye position can become more apparent. The side-focus control allows the shooter to refine focus for the target distance without changing shooting position.
The Fullfield #201533 uses advanced exposed elevation and windage turrets rather than the standard capped turrets found on the 201530 and 201531 models. The exposed configuration provides convenient access to the adjustments for shooters who prefer dialing rather than relying exclusively on reticle holdovers.
Both elevation and windage use 1/4 MOA clicks, with 72 MOA of total adjustment available in each direction.
The Fullfield is built from a single piece of aluminum with metal-on-metal components and a double-spring turret system. This construction is designed to withstand heavy use and recoil while providing reliable performance in demanding hunting conditions.
The 1-inch main tube keeps the scope compatible with a wide range of conventional 1-inch scope rings and mounts.
Burris Knob Synergy® allows the elevation knob to be upgraded to more advanced adjustment systems. Compatible configurations include custom ballistic knobs and zero-click-stop options, giving shooters the ability to further customize the scope as their shooting requirements evolve.
The Burris Fullfield 3-12x42mm #201533 is the Fullfield 3-12x42mm configuration for shooters who want an illuminated reticle, adjustable parallax and exposed adjustment turrets in a compact hunting scope.
Compared with the 201530 Ballistic E3 and 201531 Plex models, the 201533 adds Wind Ret illumination, side-focus parallax and advanced exposed turrets. Those features make it the more adjustment-oriented option for hunters and shooters who expect to dial elevation and account for wind at varying distances.
