A Tru-Brite Scope gives the option to choose reticle colors depending on the shooting situation. Red or green can be used in low-light conditions or black without illumination in broad daylight. Solid, one-piece aluminum construction, rubber coated speed-focus eye-piece, scratch resistant finish and 1/4 MOA, coil spring windage and elevation adjustments add to the durability of this scope. Multi-coated lenses for exception light transmission in all conditions and the nitrogen filled tube makes it water, fog and shockproof. Rheostat control with 5 intensity settings is controlled with the included 3V lithium batteries. Includes see-through, flip open lens caps and a limited lifetime warranty.
