    The first ACOG model, known as the TA01, was released in 1987. [3] [4] An example was tested on the Stoner 93 in the early 1990s by the Royal Thai Armed Forces. [5]In 1995, United States Special Operations Command selected the 4×32 TA01 as the official scope for the M4 carbine and purchased 12,000 units from Trijicon. [6]

    Tritium excretion can be accelerated further by increasing water intake to 3–4 liters/day. [11] Direct, short-term exposure to small amounts of tritium is mostly harmless. If a tritium tube breaks, one should leave the area and allow the gas to diffuse into the air. Tritium exists naturally in the environment, but in very small quantities.

    Trijicon specializes in self-luminous optics and night sights, mainly using the low-energy tritium illumination, light-gathering fiber optics and battery-powered LED. [ 1 ] [ 2 ] [ 3 ] Additionally, Trijicon is a contractor for the United States military and supplies the Advanced Combat Optical Gunsight (ACOG) and RX01 reflex sights .

    The Trijicon Corporation, famous for their ACOG prism sights that are adopted by various assault infantry branches of the United States military, uses tritium in their combat and hunting-grade firearm optics. The tritium light source has to be replaced every 8–12 years, since it gradually loses brightness due to radioactive decay.

    en.wikipedia.org/wiki/Tritium

    Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.3 years. The tritium nucleus (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains one proton and no neutrons, and that of non-radioactive hydrogen ...

    Tritium is only a health threat if ingested or inhaled. Since tritium is a gas, if a tritium tube breaks, the gas dissipates in the air and is diluted to safe concentrations. Tritium has a half-life of 12.32 years, so the brightness of a tritium light source will decline to half its initial value in that time.

    Under the left-hand Mil-bar, a second horizontal bar was added for judging distances, where the distance between the two bars would equate to 76 cm at 300 m. The (radioactive) tritium light source is an unstable isotope with a half-life of 12.32 years that gradually loses its brightness due to radioactive decay. It is to be replaced every 8 to ...
