Trijicon ACOG Scopes

The Trijicon ACOG (Advanced Combat Optical Gunsight) line of scopes is a battery-free, combat-proven optic specially designed for AR-15/M16/M4 weapons. 

Some of the key features of the ACOG scope include: 
  • Battery-free illuminated reticles (using tritium and on most models, a fiber-optic light pipe)
  • Legendary durabilty - Forged aluminum housing and fixed magification (no moving parts)
  • Bullet-drop compensation for quick long-range aiming adjustments
  • Bindon Aiming Concept (BAC) - all of the fiber-optic and LED ACOG scopes can be used with 2 eyes open, due to the unique brightness of the reticle (great for close quarters shooting)
