Its generous eye relief offers comfort and safety during use, even with heavy-recoiling firearms. This riflescope is compatible with Nikon’s Spot On Ballistic Match Technology, which aids in calculating exact aiming points customized to specific loads and environmental conditions. The Nikon M308 stands out as a reliable, high-performance riflescope for serious long-range shooting enthusiasts.
