Trijicon ACOG TA31 BAC 4x32mm Green Horseshoe Dual-Illuminated Scope with TA51 Mount, FDE

The Advanced Combat Optical Gunsights (ACOGs) are internally adjustable, compact telescopic sights with tritium and fiber optic dual-illuminated reticle patterns for use in low light or at night. Bindon Aiming Concept (BAC) models feature bright daytime reticles using fiber optics, which collect ambient light. The ACOGs combine traditional, precise distance marksmanship with close-in aiming speed. Designed for use with the AR-15 family, every feature of the mechanical and optical design was chosen for a single purpose: to provide increased hit potential in all lighting conditions, without failure-prone batteries.
