LaserMax LMS1151G Green Guide Rod Laser for Glock 20/20SF/21/21SF Gen 1-3 Black

Overview

The LaserMax Green Guide Rod Laser is a completely internal laser sighting system designed for Glock 20, 20SF, 21, and 21SF Gen 1–3 pistols. It replaces the factory spring guide assembly and take-down lever without requiring gunsmithing or permanent firearm modifications, allowing the user to retain their existing holsters, tactical lights, and grips. Constructed with rugged components including aircraft-grade aluminum and genuine Wolff springs, the unit features a high-intensity 520 nm green laser with a 5.0 mW output that provides a high-visibility pulsing or constant beam. Pre-aligned from the factory at 20 yards, it ensures a consistent relationship between point of aim and point of impact. Operation is controlled via an ambidextrous switch integrated into the custom take-down lever, and the unit is powered by a 393 battery.
