Trijicon ACOG Features The Trijicon ACOG 2x20mm is a fixed magnification prismatic riflescope featuring an illuminated RTR Horseshoe Red Dot reticle with dual-illumination from fiber optics and tritium providing a crisp auto-adjusting reticle brightness in daylight via fiber optics and battery-free tritium illumination in low light creating a fully illuminated sight system that operates reliably in any condition without a battery on firearms with limited mounting space including UZI H&K and MP-5 9mm submachine guns. The compact 5.30 length and 8.50 oz weight make the 2x20mm the most space-efficient fixed-magnification ACOG available and the 0.5 MOA per click external adjustment system with lanyard-capable caps enables precise zero adjustment without tools and prevents cap loss in the field. For compact firearm users submachine gun owners and serious ACOG enthusiasts who want Trijicon s combat-proven prismatic sight in the smallest available format for their space-limited platform the 2x20mm delivers the full ACOG reliability and dual-illumination capability in a compact-specific package. The Compact ACOG Mount with Q-LOC Technology is a Mil-Spec drop test-rated 6061-T6 aluminum one-handed tool-less mounting system with spring-loaded retention that maintains zero even when locking knobs are not fully tightened for reliable deployment speed and zero retention in rapid-use scenarios. The ACOG s forged 7075-T6 aircraft-grade aluminum housing is waterproof and built to withstand the most demanding operational conditions and the 2x fixed magnification provides a meaningful target detection distance improvement over iron sights while maintaining a wide enough field of view for close-quarters target acquisition. The Trijicon ACOG 2x20mm is available for sale at GrabAGun for submachine gun owners and compact firearm enthusiasts who want Trijicon s combat-proven dual-illuminated ACOG in the most space-efficient fixed-magnification configuration currently produced.
