Offering precision and reliability for the most demanding shooters, the Steiner 2.9-20x50 M7Xi Riflescope is designed for long-range accuracy and built to withstand the rigors of the field. Its wide magnification range is ideal for shorter distances at night or in exceptionally low light, useful for varmint and og hunting, with the ability to bring distant targets into sharp focus. The 34mm maintube permits greater elevation adjustment than narrower scopes and has the strength required to hold up to the recoil of high-caliber rifles. To withstand the elements, the tube is nitrogen-filled and O-ring sealed to be resistant to internal fogging and waterproof.
