Bushnell R5-1042 R5 10x42mm BaK-4 Roof Prism Green Aluminum
The Bushnell R5 10x42mm binoculars deliver serious optical performance for hunters, birders, and field sportsmen who demand crisp, bright views without breaking the bank. Built on a roof prism design with BaK-4 glass, this 10-power magnification scope brings distant game and wildlife into sharp focus, while the 42mm objective lenses gather enough light to perform in early morning and late-day conditions. The green aluminum housing is rugged enough for backcountry use, designed to survive the knocks and bumps of a hard-hunted season or a long day glassing across open country.
At 10x magnification, the R5 strikes a practical balance: enough power to pick out details at distance, but with a wider field of view and steadier image than higher-magnification models. The BaK-4 prism glass ensures edge-to-edge clarity and excellent light transmission, so what you see is true and bright even in marginal light. Whether you're spotting from a ridge, scanning timber from a stand, or tracking movement across a meadow, these binoculars keep up with the pace of hunting.
The aluminum frame adds durability and a professional feel without unnecessary weight, and the green finish blends into natural settings. This is a straightforward, reliable optic built for the field—no frills, no compromise on the fundamentals.

Frequently Asked Questions
What's the difference between 10x42 and other magnifications for hunting binoculars?
The 10x magnification pulls distant subjects in tight enough to see important details—like a buck's rack or whether a bird is the species you're looking for—while the 42mm objective maintains a reasonably wide field of view and gathers ample light for dawn and dusk hunting. Higher magnifications (like 12x) can be harder to hold steady and narrow your view of the landscape; lower power (like 8x) sacrifices some spotting range. 10x42 is the sweet spot for most field hunters.
What does BaK-4 prism glass do?
BaK-4 (barium crown glass) is a premium prism material that delivers superior light transmission and clarity compared to lower-cost alternatives. It ensures the image stays bright and sharp all the way to the edges of the lens, which matters when you're glassing across rough terrain or in dim light.
Will these binoculars work in low light conditions?
The 42mm objective lenses and BaK-4 glass are designed to perform well in early morning and late afternoon light, which is exactly when most hunting happens. They won't match a specialized low-light optic, but they're built to handle the times of day when game is most active.
