ACOG® 4×32 Tritium Riflescope with BUIS Trijicon

The Scope That Changed Everything. There’s a reason the Trijicon ACOG^® (Advanced Combat Optical Gunsight) is the official medium-distance engagement optic of the Marine Corps and U.S. Special Operations Forces.

The concept was simple; a durable scope with a reticle that illuminates in low-light and no-light situations—without requiring the use of batteries.

More than 30 years later, the original ACOG stands the test of time as one of our most popular items. Choose from many 4×32 options, including the Official Rifle Combat Optic (RCO) of the U.S. Marine Corps.

Designed to the exact specifications of the US Special Operations Command for use by elite US forces, the Trijicon ACOG TA01NSN is Trijicon’s most popular ACOG. The ranging reticle allows for bullet drop compensation out to 600 or 800 meters (model dependent) without any manual adjustments. The reticle will appear black during the daytime and will glow amber in the dark, thanks to Trijicon’s patented tritium illumination. Includes backup Iron Sights. No batteries needed! 

FEATURES

• Always On, Always Ready
  Most ACOG® models are battery free, featuring a tritium/fiber optic illuminated reticle that automatically adjusts the brightness based on available light.

• Take Control
  Several ACOG models are designed with a user adjustable brightness setting powered by a single AA battery. The 3.5×35 LED and 4×32 LED models both offer six adjustable brightness settings.

• Rugged, Reliable Housing Design
  Fixed-power design allows for minimal moving parts to create a nearly indestructible sighting system.

• “Both Eyes Open” Design
  “Both eyes open” shooting using The Bindon Aiming Concept (BAC) allows for improved situational awareness.

• Outstanding Clarity
  The quality of the glass and multi-coated lenses maximize light-gathering capabilities and clear field of view with zero distortion.

• Exact Target Distances & Hold
  Most ACOG models feature a bullet drop compensating and target-ranging reticle for decisive aiming.

• Combat Proven
  No other magnified optic has been used more in combat than the ACOG.

• Shock-Resistant

  Proven to withstand recoil from a .22LR to a .50BMG and everything in between. Easily passes U.S. Military drop test requirements.

• Waterproof
  Exceptional waterproof performance that exceeds military standards. Dry nitrogen-filled to eliminate fogging. This optic is tested to withstand and perform in extreme cold and heat with dry-nitrogen filled housing that mitigates fogging.
