Burris Fullfield IV 3-12×56 mm 30 mm Tube Second Focal Plane (SFP) Rifle Scope Review

A Close Look at the Burris Fullfield IV 3-12×56 mm 30 mm Tube Second Focal Plane (SFP) Rifle Scope

The Burris Fullfield IV 3-12×56 mm 30 mm Tube Second Focal Plane (SFP) Rifle Scope is designed to excel in challenging light conditions, a crucial factor for any serious shooter. Its robust build and advanced optical features aim to provide a competitive edge when visibility is paramount. This optic caught my attention when I was looking for a reliable scope to pair with a new rifle, specifically for hunts that often extend into twilight hours.

My previous experiences with optics, while varied, often left me wanting more in low-light scenarios. I had been using Vortex scopes, but I found myself increasingly drawn to Burris for their reputation of durability and value. The need for a scope that could gather ample light without breaking the bank was a primary driver for this purchase.

Upon unboxing, my initial impression was one of solid construction. The matte black finish felt durable, and the scope possessed a reassuring heft that spoke of quality materials, likely aircraft-grade aluminum as specified. It felt substantial without being overly cumbersome. While I considered other brands, the combination of a large objective lens, illuminated reticle, and Burris’s well-regarded warranty made the decision easier. My first reaction was a sense of anticipation, a quiet confidence that I had found a solid performer.

Real-World Testing: Putting Burris Fullfield IV 3-12×56 mm 30 mm Tube Second Focal Plane (SFP) Rifle Scope to the Test

First Use Experience

I initially mounted this optic on a new Tikka T3x in .243 for some target practice and eventually a few whitetail hunts. The testing ground was my local shooting range, as well as the deer woods of upstate New York during the early muzzleloader and later rifle seasons. Conditions ranged from crisp, clear autumn days to overcast, damp mornings and the dreaded dusk that often signals the end of legal shooting light.

The large 56mm objective lens was immediately noticeable, pulling in a surprising amount of ambient light even when the sun was low or obscured by clouds. The illuminated reticle proved invaluable during those critical minutes at dawn and dusk; setting the illumination to a moderate level, around 6 or 7, made identifying the reticle center effortless without washing out the target. I was particularly impressed with how quickly I could acquire targets compared to scopes with smaller objective lenses or non-illuminated reticles.

Ease of use was fairly intuitive. Adjusting the magnification ring required a firm but smooth twist, and the illuminated reticle control knob, while functional, was a tad stiff for my liking – a minor point I’ll elaborate on later. Overall, the transition from mounting to actual use was seamless, with no significant learning curve beyond familiarizing myself with the reticle’s holdover points.

Extended Use & Reliability

After several months of regular use, including multiple range sessions and a couple of hunting trips, the Burris Fullfield IV 3-12×56 mm has proven itself to be a reliable performer. It has held zero exceptionally well, even after being transported in a rifle scabbard and subjected to the occasional bump. This is a significant win, especially considering I’ve had scopes in the past that required re-sighting after rough handling.

Durability is where this scope truly shines for its price point. The aircraft-grade aluminum construction feels robust, and aside from minor cosmetic scuffs on the turret caps from occasional handling, there are no signs of structural wear or performance degradation. The lens coatings appear to be holding up well, maintaining their clarity and anti-reflective properties, which is crucial for light transmission.

Maintenance is straightforward. Cleaning the exterior with a microfiber cloth and lens cleaner for the glass is all that’s typically required. The seals appear to be effective; it’s been through light rain and remained fog-free internally, which is a testament to its waterproof and fogproof construction. Compared to some budget optics that might develop internal haze or develop stiffness in their adjustment knobs over time, this Burris feels like it’s built for the long haul.

Breaking Down the Features of Burris Fullfield IV 3-12×56 mm 30 mm Tube Second Focal Plane (SFP) Rifle Scope

Specifications

The Burris Fullfield IV 3-12×56 mm 30 mm Tube Second Focal Plane (SFP) Rifle Scope boasts a range of specifications designed for versatility and low-light performance. Its 56 mm objective lens diameter is a standout feature, serving as the primary light-gathering component. This is complemented by a 3x to 12x variable magnification range, offering flexibility from closer engagements to more extended shots. The 30 mm tube diameter is another key specification, providing a wider internal erector system which typically translates to more adjustment range for both windage and elevation, often quoted as 100/100 MOA of W/E travel.

The Ballistic E3 reticle, situated on the Second Focal Plane (SFP), is designed for ballistic compensation, meaning the subtensions remain constant regardless of magnification. This is a crucial distinction for shooters who rely on these holdover points for accurate shooting at varying distances. The red illumination is an LED type, powered by a common Lithium battery, and offers several brightness levels for different lighting conditions. With an exit pupil of 5.4 – 13.7 mm, it ensures adequate light transmission for comfortable viewing, especially at higher magnifications and in dim light.

The construction features aircraft-grade aluminum, contributing to its 24 oz weight and 14.5-inch length. This material choice is standard for quality optics, offering a good balance of strength and weight. The scope is rated as waterproof and shockproof, further enhancing its suitability for field use. Eye relief is a generous 3.5 – 3.8 inches, providing ample clearance to avoid scope bite, especially with heavier recoiling firearms. The parallax is free at 100 yards, simplifying aiming by ensuring the reticle and target are on the same optical plane. The adjustment click value is 1/4 MOA, offering precise adjustments for dialing in shots.

Performance & Functionality

The core job of this Burris optic—providing a clear, bright, and accurate sight picture—is handled exceptionally well, particularly considering its price. The 56mm objective lens is the hero here, delivering truly impressive low-light performance. I’ve found myself able to make ethical shots in conditions where other scopes would have rendered the target a mere silhouette. The clarity of the glass is crisp, and the edge-to-edge sharpness is surprisingly good for a scope in this class; there’s minimal distortion or chromatic aberration.

The Ballistic E3 reticle is well-suited for hunters who need quick holdovers without complex calculations. The red illumination is distinct and can be adjusted to be visible even in bright daylight if needed, though its real strength is in dawn and dusk. The positive clicks on the turrets are a significant plus; they are audible and tactile, giving confidence that each adjustment is being made accurately. Tracking has been excellent in my testing; after sighting in, I deliberately dialed corrections for longer distances and then returned them to zero, and the point of impact remained consistent.

The main strength is undoubtedly its light-gathering capability, making it an excellent choice for hunters who frequently face challenging lighting conditions. The 30mm tube provides ample adjustment range, which is beneficial for longer-range shooting or when zeroing at extreme distances. A minor weakness, however, lies in the stiffness of the magnification ring and the illumination control knob. While they function perfectly, they require a bit more force than I’d prefer, which can be a slight inconvenience when quickly changing magnification or adjusting reticle brightness in the field. This is a common trade-off in some optics to ensure robust seals and durability.

Design & Ergonomics

The Burris Fullfield IV 3-12×56 mm exhibits a functional and utilitarian design, prioritizing performance over flashy aesthetics. The matte black finish is standard for optics and helps reduce glare, a crucial factor in the field. The build quality feels solid, with no creaks or flex when handling. The anodizing is even and appears durable enough to withstand regular use without easily scratching.

Ergonomically, the scope is well-balanced. The magnification ring has a moderate amount of texture for grip, though as mentioned, it can be a bit stiff. The diopter adjustment ring at the eyepiece is also textured and moves with sufficient resistance to stay in place once set. The placement of the illumination control is intuitive, though its small size and stiffness can make it slightly fiddly with gloves on. The large objective bell, while excellent for light gathering, does add bulk and requires appropriate mounting solutions, such as higher rings, to ensure clearance for the bolt handle, especially on certain rifle actions.

Durability & Maintenance

Based on my experience and the materials used, this Burris optic is built for longevity. The aircraft-grade aluminum construction provides a strong foundation, and the seals, indicated by its waterproof and fogproof ratings, appear to be robust. I anticipate it will withstand years of regular use on a hunting rifle without issue.

Maintenance is refreshingly simple. A quick wipe-down of the exterior and occasional lens cleaning with a microfiber cloth are sufficient. There are no external adjustments that require lubrication or special care. The LED illumination is powered by a common Lithium battery, making replacements readily available. The primary concern for long-term durability would be potential damage to the lenses or internal mechanisms from severe impact, but the shockproof rating suggests it can handle typical field-related stresses.

Accessories and Customization Options

The Burris Fullfield IV 3-12×56 mm typically comes with a lens cloth and a protective lens cap set, which is a standard but appreciated inclusion. Beyond that, the primary “customization” comes in how it’s mounted and the reticle itself. The 30mm tube is compatible with a wide range of 30mm scope rings and mounting systems, allowing for significant flexibility in how it’s attached to a rifle and ensuring proper eye relief.

While the scope doesn’t come with specialized turrets for custom ballistics, the Ballistic E3 reticle is designed to provide holdover points for common calibers, effectively serving as a built-in ballistic compensation system. For those who prefer extreme customization, there are aftermarket turret systems available for many Burris scopes, though this specific model might require specialized options if available. The Second Focal Plane (SFP) reticle means that the holdover points are accurate at the highest magnification setting (12x), which is a critical functional aspect rather than a cosmetic customization.
