Trijicon
The Trijicon ACOG 4x32 RCO TA31-D-100582 is the TA31USN-M855 Advanced Combat Optical Gunsight - the USN-designated ACOG configuration compatible with both the M16A4 20-inch barrel and M16/M4 14.5-inch barrel weapon systems, delivering the unique horseshoe dot BAC reticle with Bullet Drop Compensator calibrated out to 1,000 meters in the battery-free dual illumination platform that military professionals worldwide have trusted through decades of operational deployment.
The Trijicon TA31 TA31-D-100582 unique horseshoe dot reticle pattern provides quick target acquisition at close combat ranges through the BAC both-eyes-open instinctive sight picture - the open horseshoe draws the eye immediately to the aiming area for fast close-range engagement, while the center dot delivers enhanced target identification and hit probability at the distances that the 1,000-meter Bullet Drop Compensator calibration covers. The both-eyes-open design keeps the operator's full situational awareness intact during active engagements across the platform's full engagement range.
The TA31 RCO dual illumination system uses fiber optics to self-adjust reticle brightness in daylight based on ambient lighting conditions - and tritium illuminates the aiming point in total darkness, with no batteries required. The aiming point is always illuminated without any preparation, activation, or battery management - the always-on reliability that operational users specifically depend on.
The Trijicon 4x32 ACOG TA31-D-100582's compatibility with both the M16A4 20-inch and M16/M4 14.5-inch barrel configurations gives this ACOG flexibility across the primary military service rifle platforms that the USN designation was designed to serve.

With over one million produced, Trijicon’s Advanced Combat Optical Gunsight, better known as the ACOG has become iconic in the realm of combat optics — and for good reason, the ACOG has an unquestioned reputation for quality and reliability. The Trijicon ACOG is the official medium range weapon sight for both U.S. Special Operations Forces and the Marine Corps as well as being the optic of choice for law enforcement agencies across the country. What sets the ACOG apart from the pack is what it offers to its users, increased hit potential regardless of light conditions. This is due to the tritium/fiber optic illuminated reticle found in most Trijicon ACOG riflescopes, this automatically adjusts illumination of the reticle based on available light. With a wide array of magnification levels, reticle designs, and reticle colors available — there truly is an ACOG for every mission.
