The 5-25x58 ER-25 Riflescope from US Optics is a versatile scope with low-profile exposed turrets, a wide zoom range, and large objective lens. The combination of zoom and objective makes it ideally suited for medium to extreme long ranges, especially at dawn/dusk or in forests with a heavy canopy. Its anti-reflection fully multicoated optics minimize light loss and maximizes light transmission for bright images with true color representation. Improving the scope's accuracy is an illuminated ranging reticle with 12 intensity levels that ensure the proper brightness based on personal preference or conditions.
Designed to withstand the rigors of the trail and recoil, the 6061-T6 aluminum alloy housing features a 34mm main-tube, has a matte-black Type III hard anodized finish to be scratch and corrosion-resistant, and is o-ring sealed for water and fogproof performance. The turrets have dual rebound springs that insure repeatable, reliable and accurate adjustments throughout the life of the scope.
Optimized for extreme long range use, especially in low-light conditions such as dawn/dusk or in forests with a heavy canopy
