Discovery Optics ED-ELR 5-40X56SFIR FFP 1/20MRAD Zerostop 35mm Rifle Scope
With an impressive magnification range of 5x to 40x, this scope allows you to engage targets at extremely long distances with ease. The large 56mm objective lens maximizes light transmission, providing bright and clear images even in low light conditions. The robust 35mm tube diameter enhances the structural integrity of the scope, ensuring durability and long-lasting performance.
The FFP reticle is a standout feature, maintaining zero and accuracy across the entire magnification range. This means your point of impact will not shift as you change magnification, giving you precise targeting every time. Our high definition lens system, combined with SFIR lenses, delivers edge-to-edge clarity and exceptional brightness, providing you with a sharp and vivid view of your target.
Inside the box, you'll find everything you need to maintain and calibrate your scope for optimal performance. The package includes the scope body, objective lens caps, eyepiece caps, a lens cloth, a cleaning pen/brush, an Allen wrench set, a triangular leveling base, a sunshade, and mounts. Additionally, you'll receive a user manual with setup, use, and maintenance instructions, a warranty registration card to activate your limited lifetime warranty, and flip-open lens covers to protect the lenses when not in use.
