Green Guide Rod Laser for Glock Gen 4 Model 20, 21, 41

Description

The Glock 20 Gen 4 green laser replaces the factory recoil spring guide assembly with a high-intensity internal green laser sight. Designed for Gen 4 Glock 20, 21, and 41 pistols, it installs easily with no gunsmithing required.

Glock 20 Gen 4 Green Laser Performance

The Glock 20 Gen 4 green laser is engineered specifically for Glock 20 (Gen 4), Glock 21 (Gen 4), and Glock 41 (Gen 4) pistols. The LMS-G4-1151G replaces the factory recoil spring guide assembly with a rugged internal green laser sighting system built for advanced target acquisition.

Its proximity to the bore provides maximum POA/POI accuracy and consistent alignment for center-of-mass shots.

Rugged Internal Construction

Constructed with aircraft-grade aluminum and genuine Wolff springs, this Guide Rod Laser is built for long-term durability and dependable performance.

The internal design:

• Does not restrict grip selection
• Does not interfere with holster compatibility
• Preserves factory ergonomics

Because the laser replaces the factory guide rod assembly, there are no external mounting components altering the pistol’s profile.

Programmable Green Laser Output

The high-intensity green laser is user programmable for:

• Pulsing beam
• Steady beam

A distinct ambidextrous ON/OFF switch reinforces safe firearm handling and allows intuitive activation from either side.

The system is factory-aligned to stock ballistics to ensure consistent POA/POI accuracy right out of the box.
