Trijicon ACOG TA31-D Rifle Scope 4x 32mm Dual-Illuminated Red Chevron 223 Remington Reticle with TA51 Flattop Mount Cerakote Flat Dark Earth

The Advanced Combat Optical Gunsights (ACOGs) are internally adjustable, compact telescopic sights with tritium 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.
