Features of Trijicon TA55 ACOG 5.5x50 Chevron .223 Reticle Rifle Scopes:


  • Military-Grade Aluminum Alloy Housing Forged 7075-T6 aircraft aluminum alloy housing provides for a nearly indestructible sighting system
  • Binding Aiming Concept (BAC) Trijicon ACOG models equipped with BAC allow use of the both-eyes-open aiming method along with scope magnification sighting for rapid target acquisition - in any light
  • Longer Eye-Relief Maximum eye-relief for larger caliber rifles and large exit pupil for faster target acquisition
  • Internally Adjustable Since only the prism housing moves, the ACOG is much more rugged than the conventional designs
  • Trijicon Fiber Optics Automatically adjusts the brightest level and contrast of the reticle to available light conditions
  • Trijicon Tritium Phosphor Lamp Aiming reticle glows in low-light conditions for quick target acquisition. Lamp is guaranteed to illuminate up to 15 years.
  • Totally Battery-Free ACOG delivers increased hit potential in all lighting conditions - without the use of failure-prone batteries
  • Broad Band Anti-Reflective Coated Lenses Multi-coated lenses provide superior clarity and light gathering capabilities with zero distortion
