The Trijicon ACOG 2×20 Compact is the little brother in the ACOG lineup, purpose-built for pistol caliber carbines and short 9mm platforms where a full-size optic just doesn't fit. It runs a fixed 2x magnification through a 20mm objective, which is the sweet spot for the close-to-medium ranges a 9mm PCC actually lives in. This particular model (TA47-C-400410) uses a red dual-illuminated RTR reticle calibrated for 115 and 147 grain 9mm loads, and it ships with the Trijicon Q-LOC quick-detach mount.
Like every ACOG, this one is battery-free. Trijicon combines a tritium phosphor lamp with fiber optics to keep the reticle lit no matter the conditions. In daylight the fiber optic gathers ambient light and automatically dials brightness to match your surroundings, and when the sun drops the tritium takes over and glows on its own. There's nothing to switch on, no batteries to remember, and no dead optic at the worst possible moment. The forged aluminum housing has minimal moving parts by design, which is a big part of why the ACOG has earned its reputation for being close to indestructible.
The RTR (Rapid Target Reticle) uses a horseshoe-and-dot layout built around 9mm ballistics, so your holds line up with what the round is doing downrange. Because it's a true 2x optic, you can shoot both eyes open using Trijicon's Bindon Aiming Concept, which keeps your peripheral vision open for fast target acquisition in tight spaces. Windage and elevation adjust in 1/2 MOA clicks with hand-adjustable turrets.
The included Q-LOC mount is a Mil-Spec drop-tested 6061-T6 aluminum design with a tool-less, one-handed clamping system. It's spring-loaded, so it holds retention and keeps zero even before you fully cinch it down, and it returns to zero reliably if you pull it off and put it back on. It clamps to any Mil-Spec or NATO Picatinny rail. At roughly 8.5 ounces with the mount and just 5.3 inches long, it keeps a short carbine feeling short.
No, it's completely battery-free. The reticle stays lit using a combination of tritium and fiber optics, with fiber optics adjusting brightness to ambient light during the day and tritium glowing on its own in low light. There's nothing to turn on and no dead battery to worry about.
The RTR (Rapid Target Reticle) is a horseshoe-and-dot pattern calibrated specifically for 9mm pistol caliber carbine ballistics, tuned around 115 and 147 grain loads. That means your aiming points correspond to actual bullet drop for a 9mm carbine, which is a big advantage over a generic dot at distance.
Yes. This model ships with the Trijicon Q-LOC quick-detach mount, a Mil-Spec drop-tested 6061-T6 aluminum design with a tool-less, one-handed clamping system. It's spring-loaded for solid retention and returns to zero reliably, and it fits any Mil-Spec or NATO Picatinny rail.
It's built for platforms with limited rail space, like 9mm pistol caliber carbines and compact subgun-style builds. The fixed 2x magnification and short 5.3-inch length work well for the close-to-medium engagement distances these guns are meant for, roughly out to 150 to 200 meters.
