The Trijicon ACOG 5.5x50 is the highest magnification configuration in the standard ACOG lineup - the 5.5x magnification and 50mm objective lens combination that gives precision-focused AR platform and designated marksman rifle shooters the maximum magnification advantage available in the ACOG family while maintaining the battery-free dual illumination and virtually indestructible construction that every ACOG configuration delivers as standard.
Maximum ACOG Magnification for Extended Precision
The TA55 5.5x magnification represents a meaningful step up from the widely deployed 4x32 configuration - the additional magnification that gives precision-oriented shooters the sight picture quality and target identification capability at extended distances that 4x begins to limit. For designated marksman applications, precision rifle competition, and any shooting scenario where the shooter needs to reach farther and identify targets more clearly than 4x allows, the ACOG scope 5.5x50 configuration provides that additional capability on the proven ACOG platform.
The 50mm objective lens, paired with 5.5x magnification, delivers the light-gathering performance required for a bright, clear sight picture at the distances this configuration covers - maintaining the optical quality that the ACOG platform is known for at the top end of the magnification range.
Flattop Chevron Reticle for Precision and Ranging
The Trijicon ACOG scope 5.5x50 flattop chevron reticle is specifically designed for precision shooting and practical range estimation - zeroed using the tip at 100 meters for the precise aiming reference that the chevron format delivers at the extended distances that 5.5x magnification enables. The 5.53 MOA chevron base width represents 19 inches at 300 meters - the same practical silhouette target ranging reference that serious field shooters use for fast distance estimation without any additional ranging equipment required. The included flattop adapter gives AR platform and flattop rifle users the correct mounting height and alignment for a proper sight picture at the ACOG's magnification level.
Battery-Free ACOG Performance
The Red Chevron Reticle 5.5x50 Trijicon rifle scope features fiber-optic and tritium dual illumination, automatically adjusting chevron brightness to available ambient light - fiber optics handles daylight, and tritium maintains the illuminated reticle in complete darkness, with no batteries required. The always-on illumination reliability that the ACOG platform has built its combat legacy around, through over one million units produced and deployed worldwide.
