Shock Buff

Description

The LaserMax Guide Rod Spacer (Shock Buff) is a precision component engineered specifically for Gen 4 Glock 20, Glock 21, and Glock 41 pistols that utilize an uncaptivated recoil spring when installing a LaserMax Guide Rod Laser system. Proper spacing is critical in these configurations to ensure correct alignment, reliable cycling, and consistent laser performance.

This spacer is designed to fill the necessary space created by the uncaptivated recoil spring setup found in certain Gen 4 Glock frames. Without the correct spacer, the guide rod laser assembly may not seat properly, potentially affecting function or installation accuracy. By restoring proper spacing, this component helps ensure the guide rod laser operates as intended.

Precision-manufactured to LaserMax specifications, the spacer supports stable laser positioning while maintaining factory-like firearm handling characteristics. Whether completing a new LaserMax installation or replacing a worn component, using the correct spacer helps preserve dependable operation and long-term performance.

Always refer to the LaserMax Operator’s Manual to confirm correct part selection and compatibility prior to installation.
Note: This spacer is intended only for Gen 4 Glock 20, 21, and 41 pistols using uncaptivated recoil springs and is not compatible with captivated spring systems, other Glock models, or non–Guide Rod Laser applications.
