Burris Fullfield 4-16x50 Plex Rifle Scope

The Burris Fullfield 4-16x50 #201553 is a versatile hunting and sporting riflescope built around a broad 4-16x magnification range, 50mm objective, and straightforward Plex reticle. The lower end provides useful magnification for general hunting and field shooting, while 16x offers substantially more target detail for longer-range shots and range work.

Its 50mm objective complements the higher magnification range by providing a large optical aperture, while the second focal plane Plex reticle maintains a consistent appearance as magnification changes. A side-focus parallax adjustment from 25 yards to infinity allows the shooter to tune the scope for different shooting distances, and standard capped turrets with 1/4 MOA adjustments keep the configuration focused on practical hunting use.

4-16x Magnification for Hunting and Longer-Range Shooting

The Fullfield 4-16x50 provides considerably more magnification than a traditional general-purpose hunting scope while retaining a useful 4x low end.

At 4x, the scope provides a 27-foot field of view at 100 yards, giving the shooter enough surrounding view for many open-country and general hunting situations. Increasing the magnification progressively narrows the field of view while making the target appear larger. At 16x, the scope provides the additional magnification needed for more precise aiming at longer distances.

This makes the 4-16x configuration particularly useful when a rifle may be used for both hunting and range shooting, or when the expected shooting distances extend beyond the typical range of a lower-powered hunting scope.

50mm Objective for Higher Magnification

The 50mm objective is well matched to the Fullfield's 4-16x magnification range. As magnification increases, exit pupil decreases. A larger objective can help maintain a useful exit pupil at higher magnification.

The Fullfield 4-16x50 produces a 10.0mm exit pupil at 4x and a 3.8mm exit pupil at 16x. The larger objective therefore provides additional optical aperture for a scope intended to be used at substantially higher magnification than compact hunting scopes with smaller objectives.

Objective diameter is not, by itself, a guarantee of image brightness or optical quality. Glass quality, coatings, optical design, and light transmission all contribute to the image delivered to the shooter's eye. The 50mm objective should instead be viewed as part of the scope's overall design for moderate- to high-magnification shooting.

Plex Reticle for a Clean Aiming Point

The Fullfield #201553 uses a Plex reticle in the second focal plane. The reticle maintains a consistent apparent size as magnification changes, providing a familiar aiming reference throughout the scope's magnification range.

The Plex design is intentionally straightforward. Rather than incorporating a large number of ballistic hold points or illumination features, it provides a clean reticle pattern that works well for conventional hunting and general-purpose shooting.

This makes the #201553 particularly suitable for shooters who prefer a traditional hunting reticle and plan to use their established zero rather than relying on an illuminated aiming point or a complex ballistic reticle.

Side-Focus Parallax Adjustment

The Fullfield 4-16x50 includes side-focus parallax adjustment from 25 yards to infinity. Adjustable parallax becomes increasingly useful as magnification increases because small differences in eye position can otherwise produce apparent reticle movement against the target.

The side-focus control allows the shooter to adjust the scope for the target distance, helping minimize parallax error and refine the sight picture across a wide range of shooting distances.

The 25-yard minimum adjustment also gives the scope useful flexibility for close-range testing and range work, while the infinity setting accommodates distant targets.

1/4 MOA Adjustments with Capped Turrets

The Fullfield 4-16x50 uses 1/4 MOA elevation and windage adjustments with 54 MOA of total adjustment in each direction. The standard capped turret configuration protects the adjustment controls from accidental movement and keeps the scope oriented toward practical field use.

Each click represents 1/4 MOA of angular adjustment. At 100 yards, one click corresponds to approximately 0.26 inches of movement, while the linear effect increases proportionally at greater distances.

The capped configuration is particularly well suited to hunters who establish a reliable zero and generally use the scope's reticle rather than making frequent external elevation adjustments in the field.

Second Focal Plane Reticle

The Fullfield #201553 uses a second focal plane reticle. The reticle remains the same apparent size as magnification changes, while the target image becomes larger or smaller.

This configuration is well suited to the traditional Plex reticle because the reticle remains visually consistent throughout the scope's 4-16x range. Shooters who prefer a simple, familiar aiming reference can use the same reticle presentation whether the scope is set at 4x for a wider field of view or 16x for maximum target detail.

Eye Relief and Field of View

The Fullfield 4-16x50 provides 3.7-4.2 inches of eye relief. This gives the shooter useful eye-to-scope distance while maintaining a clear sight picture across the magnification range.

Field of view ranges from 27 feet at 4x to 6.75 feet at 16x at 100 yards. The wide end provides a practical field of view for general hunting, while the narrow high-power view concentrates the sight picture on distant targets.

Because the field of view becomes substantially narrower at 16x, hunters should generally reduce magnification when moving through dense cover or when expecting close-range shots.

50mm Objective and Scope Mounting

The 50mm objective provides useful optical aperture for the Fullfield's higher magnification range, but its larger objective bell also needs to be considered when mounting the scope.

The correct ring height depends on the actual scope dimensions, rifle, receiver or mounting rail, and required barrel clearance. A 50mm objective does not automatically dictate a particular ring height.

The goal is to mount the scope as low as practical while maintaining adequate clearance and a comfortable, repeatable cheek weld.

Is the Burris Fullfield 4-16x50 Plex Right for Your Rifle?

The Burris Fullfield 4-16x50 #201553 is a strong choice for shooters who want substantially more magnification than a traditional 3-9x hunting scope while retaining a practical 4x low end. The combination of a 50mm objective, adjustable parallax, and 16x maximum magnification makes it particularly well suited to open-country hunting, longer-range shooting, and rifles that see both field and range use.

The Plex reticle keeps the aiming picture clean and uncomplicated, while the second focal plane design provides a consistent reticle appearance throughout the magnification range. Standard capped turrets and 1/4 MOA adjustments reinforce the scope's practical hunting configuration.

For shooters who want a 4-16x50 hunting riflescope with a traditional Plex reticle, side-focus parallax, and capped adjustment turrets, the Fullfield #201553 provides a straightforward configuration without adding illumination or a more complex ballistic reticle.
