Trijicon ACOG Illuminated 4x32mm Riflescope

The Trijicon ACOG (Advanced Combat Optical Gunsight) 4x32 BAC is a fixed power, compact riflescope with a dual-illuminated reticle (tritium and fiber optics) for domination in bright to low/no light. It comes with legendary durability and reliability and offers reticle patterns for numerous calibers. BAC stands for Bindon Aiming Concept, which means the ACOG's illuminated reticle allows aiming with 'both eyes open' for superior situational awareness.
