Bushnell R3-1042 R3 10x42mm BaK-4 Roof Prism Ranger Green
$129.95
The Bushnell R3 10x42mm binocular brings serious optical performance to hunters, bird watchers, and field spotters who demand clarity without compromise. Built around a roof prism design with BaK-4 glass, this 10x42 configuration delivers the magnification power to pick detail at distance while maintaining a usable field of view for active glassing. The Ranger Green finish blends into field conditions and suits backcountry aesthetics—it's the working optic for people who spend real time outdoors.
Roof prism binoculars like the R3 offer a sleek, straight-tube profile that's easier to pack and handle than porro designs, without sacrificing optical performance. The BaK-4 prism material ensures edge-to-edge image quality and the kind of bright, sharp view you need when conditions matter—early morning hunts, overcast days, or long glassing sessions. 10x magnification gives you reach to evaluate distant game or subjects, while the 42mm objective lens gathers enough light to keep the image clean across a range of lighting.
Whether you're glassing from a ridge, scanning from a blind, or working a migration corridor, the R3 is built for the field. Bushnell's reputation in hunting optics means this binocular is engineered for the real demands of outdoor work—not just the spec sheet.

Frequently Asked Questions
What's the difference between BaK-4 and other prism materials in binoculars?
BaK-4 (barium crown glass) is a premium prism material that delivers superior light transmission and edge-to-edge sharpness. It produces a brighter, higher-contrast image, especially in low light, compared to lower-grade materials. For hunting and field work where image quality directly affects performance, BaK-4 is the standard you want.
Is a 10x42 binocular good for hunting?
Yes. The 10x magnification gives you excellent reach to evaluate distant game or terrain, while the 42mm lens gathers solid light for early morning or late day conditions. This configuration balances magnification, light gathering, and field of view—it's a proven formula for glassing and spotting work in hunting scenarios.
What does the Ranger Green finish do?
Ranger Green is an earth-tone finish designed to reduce glint and blend into natural outdoor settings. It's also more practical and less reflective than brighter colors during field use.
What is a roof prism binocular?
A roof prism binocular uses an inline prism design that keeps the barrels straight and compact, in contrast to porro prism designs that have offset barrels. Roof prisms are easier to carry, handle, and pack into a pack without adding bulk, while still delivering quality optics when built with quality materials like BaK-4 glass.
