The Trijicon TA31 ACOG -- Advanced Combat Optical Gunsight, for the uninitiated -- is one of the most easily recognizable military optics available on the market today. Originally adopted by the US military in 1995, the ACOG is a fixed power and remarkably compact scope that combines close quarters speed with the ability to make precise hits at range. Their reputation for optical clarity and overall durability is both legendary and well deserved. To make the most of this battle-proven optic, Primary Arms has teamed up with Trijicon to offer the legendary TA31 with our new purpose-built and patent pending ACSS Aurora reticle!

The ACSS Aurora reticle is our very first foray into meter-based ranging and fire solutions. The feature-rich and intuitive reticle design is uncluttered, designed to communicate vital information in an efficient manner to not only increase first-hit probability but drastically reduce the time necessary to reach a firing solution to get that hit. From 300m and in, the illuminated chevron aiming point provides wicked-quick snap shooting capability and both-eyes open engagement, so you never lose peripheral vision. The outer tips of the chevron pull double duty as leads for targets moving 3.1mph perpendicular to the shooter. For targets moving a bit faster, the two lead dots on either side of the chevron are leads for a target hustling along at 8.6mph. Aurora even compensates for mounted targets up to 40mph!
For engagements 400m and out, the integrated bullet drop compensation and wind leads come into play. The tried and true ACSS auto-ranging system allows for near-instant range estimation, which enables rapid transition to the BDC system that offers holdovers in 50m increments out to an impressive 800 meters. The real world often involves wind, and ACSS Aurora provides full value 5 and 10mph wind holds. Is the wind a little stronger or softer, maybe coming at an angle? Use the holds as a reference point and adjust accordingly. For operators in the field, no other reticle provides the combined capabilities and intuitive use of the ACSS Aurora.
