The Level Series 1.5-6x44 Riflescope from Barska features fully multi-coated optics and an illuminated red-green MOA reticle. While the optics provide bright and clear images of your targets, the reticle allows you to get a precise aim and to adjust illumination that is ideal for the time of day. A side-mounted rheostat allows you to quickly adjust the color and brightness of the MOA reticle to better match the current environmental lighting situation. The external windage and elevation knobs allow for precise adjustments and can be locked into place to prevent any unintentional movement. The riflescope is O-ring sealed and nitrogen-purged for water and fogproof performance in extreme conditions.
