The Leica ER i scopes are the perfect all around hunting scope. They are durable with years of continuous development to adapt them to the needs of sportsmen in the field. They feature an AquaDura coating to repel dirt and water, they are constructed out of robust aluminum and purged with nitrogen to prevent internal fogging. They can be easily mounted on a host of different rifle platforms with standard tube dimensions and a generous 10cm of eye relief. They also offer the uncompromising glass quality that it is synonymous with the Leica name. With low light transmission and an illuminated reticle these scopes are able to provide quality visuals on prey at dusk and dawn.
