Hammers LPVO 1-4x20TM scope is a compact, lightweight, and low-profile scope that is capable of both rapid-fire with a super wide field of view and precision distance shooting with up to 4x magnification. Argon purged and sealed to be waterproof and fog-proof. Glass etched CQB reticle features an extremely large exit pupil for low light performance and a super wide field of view at fine-tuned 1x magnification. The highly visible CQB reticle is accurate and fast shooting from zero to 200 yards, and its large purpose-designed 60MOA circle & 5MOA center dot reticle gives instant targeting on paper or steel plates. When higher reticle contrast is needed against the target background, the reticle can be illuminated in red and green light, and illumination intensity in each color has five levels of adjustment to set up the desired contrast. For use in really close range, set up the magnification low at 1x so you can use the scope with generous 4inch eye relief like a red dot sight. The scope also includes a screw-on throw speed lever that can be installed on the magnification power ring for quick magnification change while keeping your eye on the target. External finger-adjustable turret screws are easy to adjust and can be reset to zero and locked in place when not being adjusted. Includes a strong and easy-to-use molded rubber bikini-style lens cover If you are looking for quick and reliable shooting accuracy, this is a great little scope that gives you a new level of shooting confidence. Complete and ready for use with an offset scope mount for Weaver and Picatinny rail.
