Trijicon 100229 ACOG 4x 32mm Obj 36.80 ft @ 100 yds FOV Matte Black Finish Illuminated Chevron

The 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 ACOG combines traditional, precise distance marksmanship with close-in aiming speed. Designed for use with the M16 family, every feature of its mechanical and optical design was chosen for a single purpose: to provide increased hit potential in all lighting conditions, without failure prone batteries.
