  • Description

    The Leica ER i 2.5-10x42 Riflescope feature universal magnification range which enables the use of the Leica ER i 2.5-10x42 in almost all field sports situations. With its light weight, slim construction and optional rapid reticle adjustment (BDC), it is a great companion. The comfortable field of view and outstanding optics guarantee your success, and the long eye relief makes a significant contribution to shooting safety. The illuminated dot enables you to easily see in twilight hours.

    Indestructable Construction

    The riflescopes of this series have stood the test since 2009. We have continuously developed and adapted them to the needs and demands of sportsmen and women in the field and enhanced them with additional features. The wate- and dirt-repellent AquaDura® coating completes their solid construction, and nitrogen purging reliably prevents internal fogging. You can rely on the ER models - especially in poor weather conditions.

    Ease Of Use And Reliable Focusing

    The slim ER riflescopes are particulary well balanced on the rifle and they are notable for maximum resolution and outstanding contrast. The combination of a large, effective entrance pupil and high light transmission offers optimal conditions for use at night and in the hours approaching darkness. The bright illuminated dot with a fine, sensitive adjustment provides even more safety. The unique easy handling and the intelligent “automatic power on-off” complete the list of benefits of the ER riflescopes.

      Mounting Flexibility For Every Kind Of Rifle

      The sophisticated construction allows individual mounting and perfect eye relief even with unusual rifles. With 10 cm the ER i features the longest eye relief in its class, providing additional safety. Thanks to their combination with solid and durable mechanisms and slim design, the riflescopes qualify as extraordinary and powerful hunting companions.
