The 2.5-10x42 ERi Riflescope from Leica fuses a weather-sealed housing and high-transmission lens system with a range of shooter-friendly features that help make this optic well-suited for close and mid-range targeting. Leica employs a 30mm optical path and multicoated lenses to transmit a clear image that has crisp detail and impressive brightness even during twilight hours. Complementing its optical performance, the ERi has a 4" eye relief and a 2.5-10x zoom range, making the ERi both versatile and practical.
This ERi riflescope model is configured with Leica's illuminated Ballistic reticle, which has a fine crosshair centered on four medium-weight posts. Stadia on the six o'clock post appear in 2 mil and 1 mil increments, and an alternate aiming point 0.5 mil above each stadia enable precise bullet drop compensation. The 2.5-10x42 ERi also has low-profile capped windage and elevation turrets capable of impact point corrections in 0.1 mil increments. Leica's reticle illumination system has nine brightness settings controlled by a dedicated side turret.
To preserve battery life, the ERi features two automatic deactivation functions; one that turns off the illuminated aiming point after three minutes, the other uses a built-in tilt sensor to determine when the rifle-mounted scope is raised or lowered from the firing position. Once the rifle is returned to a relatively level position (±70°), the red dot is immediately re-activated to the previously used brightness setting.
In addition to the image quality and functionality of the ERi riflescope, its nitrogen-filled aluminum housing is built for reliable performance in heavy rain, extreme humidity, and rapid temperature changes. Exposed lens surfaces are coated with AquaDura, a water-repellent layer that helps moisture roll off the lens surface and prevent occluding the scope's objective or eyepiece.
