Trijicon VCOG LED 1-8x 28mm Rifle Scope - Segmented Circle / Crosshair - The Trijicon 1-8x28 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 / MRAD crosshair dot 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), the 1-8x28 VCOG offers a battery life of 633 hours at setting 6. Choose from 11 user-selectable brightness settings, 2 night vision settings, 8 day settings, and 1 super-bright setting. An integrated dial fin allows easy rotation through the magnification range, and a near-constant eye relief means no head or stock position adjustments are needed. Waterproof to 20 meters (66 ft.).
