The Trijicon Compact ACOG 2x20 rifle scope brings proven military-grade optics to firearms where space is tight. Designed for platform-constrained setups like 9mm submachine guns, this illuminated scope delivers a fixed 2x magnification with a red 9.2 MOA triangle reticle—giving you a functional sight picture in daylight or low light without eating rail real estate. Trijicon's track record in duty optics means the glass clarity and reticle brightness you get here are built to work when it matters. This isn't a precision long-range scope; it's a close-to-medium-distance combat and tactical sight that performs.
The scope ships mounted on Trijicon's Compact ACOG Mount, a Mil-Spec aluminum platform engineered for hard use. The mount uses Q-LOC Technology—a spring-loaded retention system that maintains zero even if the knobs aren't cranked down tight, and lets you swap the optic on and off without chasing your zero. Tool-less, one-handed operation means you can mount or dismount it in the field without a multi-tool. The mount seats on any Mil-Spec or NATO Picatinny rail and has been drop-test rated to real-world standard specifications.
Construction throughout is 6061-T6 aluminum with a matte black anodized finish, kept deliberately light and low-profile so it won't throw off your gun's ergonomics or sight lines. Trijicon built this in the USA. Whether you're running a short-stroke patrol rifle, a PCB build, or a subgun platform, the Compact ACOG 2x20 is a proven glass solution for close-quarters and intermediate-distance work.

Trijicon designed this scope for firearms with limited receiver or rail space, particularly 9mm submachine guns and platform-constrained rifles. It's well-suited to any gun with a Mil-Spec or NATO Picatinny rail where you need compact, combat-ready optics without a long tube footprint.
Yes. The Trijicon Compact ACOG Mount is included with this package. It features Q-LOC Technology for spring-loaded retention and one-handed, tool-less operation.
No. The Compact ACOG Mount's Q-LOC spring-loaded design maintains zero even when the scope is dismounted and remounted, as long as you follow torque specifications. This allows you to swap optics or remove the sight in the field without recalibration.
The reticle is a red 9.2 MOA triangle that is illuminated. The triangle shape provides a large aiming point for close-to-intermediate ranges while remaining usable in low light and daylight conditions.
