Full Disclosure: Burris Fullfield E1 6.5-20x50mm 1in Tube Second Focal Plane (SFP) Rifle Scope
For years, my go-to optics for varmint control and extended-range engagements on prairie dogs have been a mixed bag, leaning towards the tried-and-true Leupold and Nitrex lines, alongside some trusty Burris Signature models. However, a persistent need for more magnification on my dedicated .204 Ruger rifles, particularly for those finicky chucks and distant prairie dog towns, had me searching. I needed something that offered more reach than my current setups without breaking the bank, and importantly, retained the optical clarity I’ve come to expect for those critical shots. My search eventually led me to the Burris Fullfield E1 6.5-20x50mm 1in Tube Second Focal Plane (SFP) Rifle Scope, a model that promised enhanced magnification and Burris’s signature quality. My initial impression upon unboxing this optic was one of solid craftsmanship; the aircraft-grade aluminum construction felt robust, and the matte finish exuded a professional, no-nonsense aesthetic. While I briefly considered some higher-end options from other manufacturers, the combination of magnification range, reticle design, and the Burris reputation at this price point made this model a compelling choice. My first reaction was a quiet sense of satisfaction, a feeling that I might have finally found the precise tool needed for my specific needs.
Real-World Testing: Putting Burris Fullfield E1 6.5-20x50mm 1in Tube Second Focal Plane (SFP) Rifle Scope to the Test
First Use Experience
My initial testing grounds for this scope were the familiar, sun-baked prairie dog fields of the Oklahoma panhandle, mounted on a precisely built .204 Ruger. The extended magnification range proved its worth immediately, allowing me to clearly identify and engage targets at distances that had previously been challenging. Even when pushing the magnification to its upper limits, the Hi-Lume Multi-Coated lenses delivered impressive clarity and light transmission, crucial for those crisp prairie dog silhouettes against the dusty terrain. Adjusting the ergonomic side focus parallax knob was smooth and intuitive, requiring minimal disruption to my shooting stance, a welcome change from some other scopes I’ve used.
Extended Use & Reliability
Over several seasons and countless rounds of .204 Ruger and .22-250, this Burris optic has cemented its place as a workhorse. The double internal spring-tension system has performed admirably, consistently holding zero through the jarring recoil of my rifles and the inevitable bumps and jostles of field transport. Cleaning and maintenance have been straightforward; a quick lens cleaning with a microfiber cloth and appropriate solution keeps the optical glass pristine, and the sealed construction ensures that dust and debris are kept out. Compared to some budget scopes I’ve experimented with in the past, the durability and consistent performance of this model are a significant step up, rivaling even some pricier alternatives I’ve owned.
Breaking Down the Features of Burris Fullfield E1 6.5-20x50mm 1in Tube Second Focal Plane (SFP) Rifle Scope
Specifications
The Burris Fullfield E1 6.5-20x50mm 1in Tube Second Focal Plane (SFP) Rifle Scope boasts a substantial 50mm objective lens diameter, a critical feature for gathering maximum light, especially in those challenging dawn and dusk hunting scenarios. Its variable magnification spans an impressive 6.5x to 20x, providing the reach necessary for identifying and engaging distant targets. The Ballistic Plex E1 MV reticle, situated on the Second Focal Plane (SFP), is designed for trajectory compensation with its cascading dots, simplifying holdovers for various distances and windage adjustments. The 1-inch tube diameter is standard and readily accepts a wide range of mounting solutions.
These specifications directly translate into practical performance. The large objective lens ensures that even at the highest magnification of 20x, the image remains bright and clear, crucial for precise shot placement. The trajectory-compensating technology within the reticle, particularly when calibrated for cartridges like the .22-250 as noted, significantly reduces the need for complex mental calculations during a shot. The SFP design means that the reticle’s subtensions remain constant relative to the target at all magnification levels, simplifying its use for ranging and holdovers without needing to account for magnification changes. The adjustable parallax, with a focus range from 50 yards to infinity, is essential for eliminating parallax error at varying distances, further enhancing accuracy.
Performance & Functionality
The primary function of any rifle scope is to present a clear, magnified image that allows for precise aiming, and this Burris optic excels in this regard. The 6.5-20x magnification range is highly versatile, offering sufficient power for identifying small targets at long range while still providing a usable field of view at lower powers for closer encounters. The Hi-Lume Multi-Coating is not just marketing jargon; it actively combats glare and enhances contrast, making it easier to pick out targets even in dappled light or against busy backgrounds. The positive steel-on-steel adjustments on the finger-adjustable turrets provide tactile feedback and, based on my experience, ensure repeatable accuracy when sighting in or making ballistic corrections.
One of the standout functional features is the Ballistic Plex E1 MV reticle. Its cascading dots offer a intuitive system for compensating for bullet drop, a feature that many users, especially those new to long-range shooting or hunting, will find incredibly user-friendly. The integrated mil-measuring tools also add a layer of ballistic utility for those who prefer to dial adjustments based on range estimation. The scope’s waterproof, shockproof, and fogproof construction, thanks to its nitrogen-filled scope tubes and durable build, means it’s ready for whatever conditions the field throws at it, a critical consideration for serious hunters and varmint shooters.
Design & Ergonomics
The Burris Fullfield E1 6.5-20x50mm 1in Tube Second Focal Plane (SFP) Rifle Scope presents a clean and functional design. Its 1-piece outer tube constructed from aircraft-grade aluminum feels solid and capable of withstanding significant abuse. The matte black finish effectively minimizes glare and blends well with most rifle stocks. The separated power ring and eyepiece design is a practical touch, allowing for the easy attachment of aftermarket lens covers, a small but appreciated detail for gear protection.
The turrets are designed for easy adjustment, offering a sleek profile while remaining accessible. While the user feedback mentions the windage and elevation clicks can sometimes be “on the light side,” I found them to be sufficiently tactile for positive adjustment. The side focus parallax adjustment is a significant ergonomic win, allowing for quick and accurate focus correction without breaking cheek weld or taking your eye off the target. This ergonomic consideration is vital for maintaining focus on fast-paced varmint situations or when adapting to changing light conditions during predator hunts.
Durability & Maintenance
Burris has a reputation for building durable optics, and the Fullfield E1 series seems to uphold that standard. The stress-free, solid 1-piece outer tube is engineered to handle the recoil of even the heaviest calibers, and my own experiences with its robust construction suggest it will endure years of hard use. The waterproof and fogproof nature, achieved through nitrogen purging, is a testament to its built-in durability, preventing internal lens fogging that can ruin a hunting trip.
Maintenance is refreshingly simple for this model. Regular cleaning of the exterior and objective/ocular lenses with appropriate tools is generally all that is required to keep it in top condition. The internal mechanisms, protected by the robust housing and spring-tension system, are designed for longevity, minimizing the need for user intervention beyond basic care. Given its construction and the Burris Forever Warranty, this scope is built for the long haul, designed to be a reliable tool for many seasons to come.
Accessories and Customization Options
While the Burris Fullfield E1 6.5-20x50mm 1in Tube Second Focal Plane (SFP) Rifle Scope doesn’t come with a plethora of included accessories, its design facilitates common customization. The 1-inch tube diameter allows for a wide selection of scope rings and bases from various manufacturers, enabling shooters to achieve optimal mounting height and alignment for their specific rifle and shooting style. The provision for flip-up lens covers is a key feature that many users will appreciate for protecting the Hi-Lume Multi-Coated lenses from the elements and accidental damage, though these are typically purchased separately.
The primary customization aspect revolves around the reticle and its application. While this specific model features the Ballistic Plex E1 MV reticle, Burris offers a range of reticles across their product lines, catering to different ballistic preferences and shooting disciplines. For this optic, the side parallax adjustment allows for fine-tuning focus, which can be considered a form of on-the-fly customization to suit target distance and shooting conditions. The finger-adjustable turrets provide a direct interface for ballistic adjustments, and while aftermarket turret caps or custom dial systems are not standard, the existing turrets are functional for their intended purpose.
