Dominate the field with Trijicon's 4x32 ACOG BAC Dual-Illuminated Rifle Combat Optic. This almost-indestructible (7075-T6 aluminum alloy body) and self-powered (battery-free) Advanced Combat Optical Gunsight (ACOG) offers a low-distortion 4x optical system and an illuminated red Horseshoe Dot ballistic reticle to help you achieve your goals. The reticle is optimized for A4/M4 ammunition and features a dual (tritium and fiber optic) illumination system that does not require any electrical power and can run for years. It automatically adapts to the environmental lighting conditions and delivers a highly visible reticle pattern. The optical system complies with the Bindon Aiming Concept (BAC), allowing you to aim with both eyes open. This ACOG provides a 1/2 MOA windage and elevation clicks, and ships with a LT799 LaRue QR mount for attachment to your firearm.
