Trijicon’s Description: ACOG 3.5×35 Scope with Circle and Red Chevron BAC reticle- features Dual Illumination (Fiber optic provides daylight illumination and tritium illuminates reticle at night).
In 1991, the Trijicon ACOG® was chosen by the U.S Navy SEALs for testing, then operations. In 1995, German GSG9 SWAT chose the 3.5×35 model for their 550 rifles. Ever since, the ACOG® 3.5×35 riflescope has remained a favorite among competitive shooters, law enforcement and freedom-loving civilians everywhere.
RKB Armory’s Opinion: This scope offers a much bigger eyebox and field of view than other popular ACOGs. If you haven’t looked through one, you’re going to be pleasantly surprised. The circle / chevron is pretty cool, too.
