Trijicon Compact ACOG 2x20 Features The Trijicon Compact ACOG 2x20 uses the Bindon Aiming Concept letting the shooter keep both eyes open while the RTR Horseshoe Red Dot reticle draws the eye naturally to the target. Illumination comes from a combination of fiber optics and tritium so the reticle brightens automatically in daylight and glows without any battery in low light or darkness. This dual illumination source means the optic never goes dark a critical advantage for a sight meant to ride on a defensive or duty firearm. Adjustments move in 0.5 MOA per click giving the shooter fine control when zeroing to a specific point of impact. Housed in forged aluminum with a matte black finish the scope measures 5.3 long and weighs just 8.5 oz keeping the overall package light on firearms with little room to spare. The included Q-LOC mount uses a Mil-Spec rated 6061-T6 aluminum design with a tool-less one-handed locking lever that maintains zero even if the mounting knobs are not fully tightened. That spring-loaded retention system is built to Trijicon s own return-to-zero standard so the optic can be removed and reinstalled without losing accuracy. Shooters equipping a compact carbine or submachine gun with a rugged low-maintenance optic will find the Trijicon Compact ACOG 2x20 a dependable choice.
