Trijicon ACOG 400415 Features The Trijicon ACOG 400415 uses fiber optics to automatically brighten the reticle in daylight while a tritium-phosphor lamp keeps it glowing in low light so the RTR Horseshoe green dot stays visible in any lighting condition without ever needing a battery change. External windage and elevation adjusters require no tools and lanyard-tethered adjuster caps prevent the loss of small parts in the field. At just 7.2 ounces and 4 inches long the compact housing keeps weight forward-friendly for fast-moving tactical teams and close-quarters competition shooters alike. Half-MOA click adjustments and a generous 2.4-inch eye relief make this ACOG easy to zero and comfortable to run under recoil. The included Trijicon Compact Mount with Q-LOC Technology offers tool-less one-handed mounting to any Mil-Spec or NATO Picatinny rail and its spring-loaded design maintains zero even if the mounting knobs loosen under recoil. Matte black anodizing on the forged aluminum body resists wear and glare in the field while the low-profile mount keeps the optic s overall footprint compact on a carbine. The package includes a Trijicon logo sticker a Scopecoat protective cover a lens pen and the full ACOG manual with warranty card. Whatever the mission the ACOG 400415 pairs Trijicon s proven combat pedigree with a mount built for rapid deployment.
