Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP) Review

One Month Later: Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP) Review

After spending a solid month with the Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP), it’s clear this optic is a thoughtful contender in its class. Manufactured by Burris, it aims to provide dedicated ballistic support for specific cartridges like the 450 Bushmaster, a niche it seems well-equipped to handle. My search for this particular scope began after my general-purpose hunting rifle felt a bit under-equipped for the slightly longer shots I’ve been encountering on my local property. While I already owned a well-loved Burris Fullfield E1 (a standard plex model), the allure of a scope specifically tuned for a cartridge known for its distinct trajectory pushed me towards this specialized variant.

Upon unboxing, the immediate impression was one of robust construction; the 1-inch main tube felt solid and the matte finish lent it a professional, no-nonsense appearance. It doesn’t scream “budget,” but rather “dependable workhorse.” My initial thought was a sense of cautious optimism; could this optic truly offer the tailored performance it promised without a significant jump in price? I’d briefly considered other brands known for their value optics, but Burris’s reputation for durability, coupled with positive feedback from fellow shooters, kept me focused on this particular model. The initial feeling was one of quiet satisfaction, a sense that this might just be the tool I needed for a specific purpose.

Real-World Testing: Putting Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP) to the Test

First Use Experience

My initial tests were conducted at a familiar outdoor shooting range, specifically set up to sight in a rifle chambered in .450 Bushmaster. The weather was crisp and clear, offering good daylight conditions, though I made a point to observe its performance as dusk began to settle. The Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP) was surprisingly intuitive to mount and bore-sight. Adjusting the magnification ring from 3x to 9x was smooth, and the reticle, designed for ballistic compensation, was distinct without being overly busy.

I quickly noted that the Second Focal Plane (SFP) design meant the reticle subtensions would remain constant relative to the target at all magnifications, a point crucial for its intended ballistic purpose. While initial focus adjustment was straightforward, I did experience some blurriness at the extreme edges of the field of view at higher magnifications, particularly when trying to resolve very fine details at 100 yards in bright midday sun. This is a common trade-off in this price bracket, but worth noting. However, the main ballistic plex markings themselves remained sharp and clear, allowing for precise aiming points.

Extended Use & Reliability

Over the past month, this optic has seen regular use, both at the range and during an extended early-season deer hunt. It’s been mounted on a rifle that’s been handled, transported, and experienced the typical bumps and vibrations of field use. The Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP) has held its zero remarkably well. After several range sessions and a significant amount of walking through varied terrain, I re-checked the zero and found it to be precisely where I left it.

Durability-wise, the scope has endured light rain and a fair amount of dust without any internal fogging, thanks to its nitrogen-filled scope tubes. The matte finish has resisted minor scuffs from brush contact. Compared to some higher-end optics I’ve used, the optical clarity, while very good for its price, isn’t quite at the level of edge-to-edge sharpness found in scopes costing twice as much. However, for its intended purpose and budget, it performs admirably. Maintenance has been minimal; a quick wipe-down with a lens cloth after each outing is all that’s been required, and the included lens caps are a practical touch for protection.

Breaking Down the Features of Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP)

Specifications

The Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP) boasts a 40mm objective lens diameter, which is a classic configuration for balancing light gathering with a relatively compact size. Its 3-9x variable magnification range makes it exceptionally versatile for a variety of shooting distances, particularly those common in hunting scenarios. The 1-inch main tube is standard and compatible with a wide array of mounting rings.

The Ballistic Plex reticle is the star here, specifically designed for cartridges like the .450 Bushmaster, featuring hash marks calibrated for trajectory compensation. It’s important to note this is a Second Focal Plane (SFP) reticle, meaning the reticle’s size does not change with magnification, ensuring consistent holdover points at all power settings. The exit pupil ranges from 5mm at 9x to 13mm at 3x, providing adequate brightness for most daylight conditions and reasonable low-light performance. This optic is non-illuminated and features no parallax adjustment, which simplifies its use but means that extreme focus needs to be managed by the shooter at longer ranges. The adjustment click value is 0.25 MOA, offering fine-tuned zeroing capabilities.

Performance & Functionality

The primary function of the Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP) is to provide a clear sight picture and accurate aiming points tailored for specific ballistic curves. Its performance in this regard is solid, especially with the dedicated ballistic reticle. The hash marks do indeed provide useful holdover points for the .450 Bushmaster at common hunting distances, making rapid follow-up shots more reliable than using a standard duplex reticle.

Strengths lie in its clear, bright optics for its price point and the effectiveness of its specialized reticle. The Hi-Lume multi-coating on the lenses does an admirable job of reducing glare and enhancing contrast, which is particularly noticeable in dappled light. A weakness, as noted in some user feedback, can be slightly reduced clarity at the furthest edges of the field of view, and the lack of parallax adjustment means that precise focusing at extended ranges requires careful attention from the shooter. For its intended use within typical hunting ranges (up to a few hundred yards), it performs well beyond its modest price tag.

Design & Ergonomics

Burris has designed the Fullfield E1 series with a focus on user-friendliness and durability. The finger-adjustable windage and elevation turrets are a key ergonomic feature, offering a sleek profile and tactile feedback for adjustments. These turrets are capped, which is a common and practical approach for hunting scopes to prevent accidental changes.

The separated power ring and eyepiece design is a thoughtful touch, allowing for the easy attachment of aftermarket flip-up lens covers, which are essential for protecting the glass in rough conditions. The durable, stress-free, solid 1-piece outer tube construction instills confidence in its ability to withstand recoil and impact. The overall feel is one of ruggedness; it’s not a delicate instrument but a tool built to survive the rigors of outdoor use.

Durability & Maintenance

The Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP) is built to last. The double internal spring-tension system is engineered to hold zero through significant shock, recoil, and vibration, a claim that my month of use has supported. The positive steel-on-steel adjustments are crucial for repeatable accuracy and contribute to the overall longevity of the scope’s mechanical function.

Cleaning is straightforward: a soft cloth for the lenses and a damp rag for the exterior. The nitrogen-filled tubes prevent internal fogging, which is a critical feature for hunting in variable weather. The main concern for long-term durability would likely be the integrity of the seals and O-rings over many years of extreme temperature fluctuations or submersion, though for typical hunting scenarios, it is very robust.

Accessories and Customization Options

This Burris Fullfield E1 3-9x40mm 450 Bushmaster Rifle Scope, 1in Tube, Second Focal Plane (SFP) comes with basic but essential accessories, most notably a pair of lens caps. These are crucial for protecting the objective and ocular lenses from dust, scratches, and environmental elements during transport and storage. While the scope itself is not heavily customizable in terms of its internal mechanisms or reticle choices (this is a specific Ballistic Plex model), its 1-inch main tube allows for a wide range of aftermarket mounting solutions.

Users can easily pair it with various rings and bases from brands like Burris themselves, Leupold, Talley, and many others, ensuring a secure fit to their rifle. The separated eyepiece and power ring also readily accept flip-up lens covers, which are a highly recommended addition for any serious hunter or shooter.
