Burris Fullfield IV 3-12x42mm Illuminated Matte Rifle Scope

The Burris Fullfield IV 3-12x42mm illuminated matte rifle scope brings five decades of refinement into a compact, dependable optic built for hunters and shooters who demand reliability across diverse hunting platforms. With its improved 4x optical system and premium multi-coated lenses, this scope delivers edge-to-edge clarity and low-light performance when it matters most—whether you're glassing timber at dawn, taking a shot through overcast skies, or working with air rifles, slug guns, or centerfire rifles. The 42mm objective balances light-gathering capability with a trim profile that won't add unnecessary heft to your rifle.

Built to endure hard use, the Fullfield IV is nitrogen-filled to ensure waterproof, shockproof, and fog-proof performance in rain, dust, and temperature swings. Its recoil-resistant design handles the impact of everything from modest .243 Winchester loads to heavy magnums without losing zero or optical integrity. The redesigned turret knobs are finger-adjustable, making windage and elevation corrections quick and intuitive in the field without tools or gloves off.

The illuminated Ballistic E3 reticle gives you hold-overs for extended-range hunting while the center illumination makes the reticle visible in dim conditions. At 3-12x magnification, you get 3x power for close-range situational awareness and 12x for precise target evaluation and accurate shot placement at distance. This is a scope that works equally well on a varmint rifle, a hunting rifle, or a precision .22 for training and small-game pursuits.

Every Burris scope ships with the Burris Forever Warranty, giving you peace of mind that your optic is backed by a company that stands behind its products for life.

Specifications

Frequently Asked Questions

What rifles is this scope compatible with?

The Fullfield IV 3-12x42mm is rated for recoil from air rifles, slug guns, and high-caliber centerfire rifles. Its 30mm tube diameter is standard across most modern rifle platforms, and you'll need standard 30mm rings to mount it. If you're unsure about fit on a specific rifle, reach out to our team.

Is the illuminated reticle visible in bright daylight?

The illuminated Ballistic E3 reticle shines brightest in low-light conditions—dawn, dusk, and overcast skies. In bright daylight, the illumination is still present but less critical since ambient light naturally highlights the reticle. Most hunters run the illumination on a lower brightness setting during the day and dial it up as light fades.

What does the Ballistic E3 reticle offer for range estimation?

The Ballistic E3 is designed with hold-over points to support extended-range shooting. The exact distance for each hold-over varies by load and cartridge, so you'll want to confirm your specific ballistic solution at the range or through a ballistics calculator before hunting.

Is this scope waterproof if it gets submerged?

The Fullfield IV is nitrogen-filled and fog-proof, meaning it handles rain, humidity, and temperature swings without fogging internally. The nitrogen pressurization also helps it withstand accidental submersion, but we recommend treating it with the same care you'd give any precision optic—rinse with fresh water and dry if it takes a dunking, and inspect the turrets and erector tube for signs of water intrusion.
