A low-magnification gunsight; made smaller and lighter for close combat and fast moving teams. Now with Ring & Dot Reticule in brilliant Green.

Big performance, and even more speed…wrapped in a smaller package. At just 4.5 ounces, and only 4” long, this ACOG is perfect for fast-moving tactical teams operating in close quarters; or for speed-oriented competition. The extra compact ACOG TA44S has a short M16 Handle Mount that requires less space on your weapon, while providing significantly improved fire control capability and faster reaction time. Or the scope can be converted to rail-mounting for a lower profile, or to fit any universal rail-equipped weapon, with the optional TrijiconTA60 Compact ACOG M16 Flattop Adapter. No matter what platform you prefer, the low magnification, large 7.4° field of view, and eye-friendly design of the crystal clear roof-prism 1.5 x 16 optic make targets easier and quicker to acquire.
  • Just 4 in., 4.5 oz.; this very compact scope boosts fire control capability for M16/M4-style, weapons with handle or rail mounts*
  • Low magnification, wide 7.4° field of view, and eye-friendly design allow “instinctive” target acquisition at close-to-medium range
  • Dual-illuminated reticle is visible in any light, without batteries
  • Highly visible Green Ring & Dot reticles enhance Trijicon’s innovative both-eyes-open BAC aiming method
  • Military-grade aluminum alloy housing makes ACOG nearly indestructible and waterproof to 500 ft.

Advanced Combat Optical Gunsight—Hit Fast in any light. Designed for use with the M16 family, every feature of the ACOG’s mechanical and optical design was chosen for a single purpose: to provide increased hit potential in any light, under the toughest combat and tactical conditions—without failure-prone battery-powered illumination systems. Rugged, dependable, battle-proven Trijicon ACOG systems are internally-adjustable compact roof prism telescopic sights with battery-free dual illuminated reticles, powered by a patented combination of fiber optic and tritium-based technology. Day or night, a Trijicon ACOG can measurably increase your ability to make faster “instinctive” shots with marksman precision. What’s more, most ACOG reticules are compatible with Trijicon's exclusive Bindon Aiming Concept™, an innovative both-eyes-open aiming method that uses scope magnification for quicker target acquisition in any light. It can provide a huge advantage against fast-moving targets, especially during stressful low-light situations.

Ranging is built into many of its reticles, allowing users to set zero and never worry about it again. And a rugged, forged aluminum housing makes it nearly indestructible.
