Trijicon ACOG® 3.5x35 TA11, a Trijicon x NOVELARMS joint development (released late May to early June 2025)

Trijicon x NOVELARMS joint development

Reservations made between March 5th and March 18th will be accepted and the product will be made to order.

Until now, ACOGs have not been sold or allowed to be used in Japan because the tritium content used to illuminate the reticle exceeds domestic regulations. However, thanks to the collaboration between Trijicon and Novelarms, an ACOG that meets Japanese regulations will now be released! Don't miss this opportunity!

US Navy SEALs Model: Trijicon ACOG® 3.5×35 Riflescope

In 1991, Trijicon ACOG® was tested and subsequently selected for service by the U.S. Navy SEALs. In 1995, Germany's GSG9 SWAT selected the 3.5x35 model for their .550 rifle. Since then, ACOG® 3.5x35 riflescopes have been a favorite among competitive shooters, law enforcement, and freedom-loving civilians everywhere.

ACOG (Advanced Combat Optical Gunsight) riflescopes are specifically designed for military applications and are ideal for users who require the right combination of magnification, low-light capability and long eye relief for rapid target identification and maximum situational awareness.

Equipped with the Bindon Aiming Concept (BAC), it allows you to operate with both eyes open. The ACOG model requires no batteries. It features fiber optics and a tritium fluorescent lamp. The fiber optics uses ambient light to automatically adjust the reticle's brightness level and contrast to available light conditions, while the tritium fluorescent lamp remains lit in dark places. It's truly "ALWAYS ON, ALWAYS READY" - always ready.

The fixed-output design minimizes moving parts for a targeted system. The quality of the glass and multi-coated lenses ensures light-gathering capabilities and a clear, distortion-free field of view. It features bullet compensation and a target-ranging reticle for decisive aiming. The rugged body is constructed from forged 7075-T6 aircraft-grade aluminum alloy, easily passing U.S. military drop-test requirements. Its waterproof performance exceeds military standards, and its dry-nitrogen-filled housing reduces fogging, allowing it to withstand extreme cold and heat. As of 2023, it remains in service with the U.S. Marine Corps and many other military forces.

About Tritium

Industrial products that use tritium are regulated by the Atomic Energy Basic Act (Act No. 167 of 1957, Act on the Regulation of Radioactive Isotopes, etc.).

Under current law, the sale and use of products containing 1,000 MBq or more of tritium is prohibited.

The Trijicon ACOG® (Advanced Combat Optical Gunsight), sold exclusively by Nobel Arms, is a legal product with a tritium content set at 27 millicuries (999MBq), and is stamped with "LT" on the product itself.
