The Bushnell R5-1042 delivers professional-grade optical performance with 10x magnification and 42mm objective lenses for superior light gathering in challenging conditions. Advanced BaK-4 roof prism construction ensures maximum light transmission and crisp edge-to-edge clarity across the entire field of view.
What Makes This Different
The R5 series incorporates premium BaK-4 prism glass instead of standard BK-7 material, providing 15% better light transmission and eliminating the dark shadows typically seen in budget optics. Fully multi-coated lenses reduce glare and enhance contrast in low-light situations. The durable green rubber armor coating offers secure grip and impact protection while maintaining a low-profile appearance in outdoor environments.
