Trijicon TA339 ACOG 3x 30mm Obj 1.9" Eye Relief Chevron Shape Black

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 ACOGs combine 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.
