Trijicon VCOG LED MIL 1-6x 24mm Rifle Scope - Segmented Circle / Crosshair - The Trijicon 1-6x24 VCOG (Variable Combat Optical Gunsight) is a highly rugged, variable magnification riflescope designed for close quarter battle (CQB) and long distance marksmanship. With a forged aircraft-grade 7075-T6 aluminum housing, the VCOG is nearly indestructible. Superior glass provides exceptional clarity and color with zero distortion. The universal segmented circle/MIL reticle is designed for multi-platform use, accommodating multiple calibers, ammunition weights, and barrel lengths. The first focal plane reticle allows subtensions and drops to remain true at any magnification, allowing the shooter to quickly and accurately apply the correct hold. With ruggedized electronics, the LED reticle is robust enough for any application. Powered by a lithium AA battery (provided), it has 6 user-selectable brightness settings. The green LED boasts a battery life of 1,400 hours at setting 4 (constant on); the red LED has a 700 hour battery life. An integrated dial fin allows easy rotation through the magnification range, and a constant eye relief means no head or stock position adjustments are needed. Waterproof to 20 meters (66 ft.).
