Slim construction is a characteristic feature of both ER i riflescope models. A short eyepiece and long tube provide plenty of latitude for precision mounting on every type of rifle. The extra bright ER i 3-12x50 riflescope features up to 12x magnification and establishes ideal pre-conditions for precise shots at more distant targets. On request the ER i 3-12x50 can be supplied with rapid reticle adjustment (BDC).

      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.
