Duration: 15:44

The Brass Facts review of the GL4 Pro laser aiming module highlights its quad-functionality (Visible Laser, IR Laser, IR Illuminator, White Light) and innovative front-access battery compartment. However, significant drawbacks include a non-tactile mode selector, a sensitive QD mount prone to zero shift, and an IR illuminator that is overly flood-like, causing self-blinding and limited effective range. The white light is considered mediocre.

Quick Summary

The GL4 Pro IR laser module features a quad-function design with visible/IR lasers, IR illuminator, and white light, plus a convenient front-access battery compartment. However, it suffers from a non-tactile mode selector, a problematic QD mount prone to zero shift, and an overly flood-like IR illuminator that limits effective range and can cause self-blinding.

Frequently Asked Questions

What are the main issues with the GL4 Pro IR laser?

The GL4 Pro has several issues, including a non-tactile mode selector, a sensitive QD mount that can cause zero shift, and an IR illuminator that is too flood-like, limiting its effective range and potentially blinding the user. The white light is also considered mediocre.

What is the advantage of the GL4 Pro's battery access?

The GL4 Pro features a front-access battery compartment by twisting the bezel. This design allows for battery changes without removing the unit from the firearm, thus preserving the zero, which is a significant improvement over many competing models.

How does the GL4 Pro's IR illuminator perform?

The GL4 Pro's 35 M IR illuminator is powerful but designed as a flood light. This means it scatters light broadly in front of the user, limiting effective target illumination at longer distances and potentially causing self-blinding or blinding friendly forces.

Is the GL4 Pro's QD mount reliable?

The QD mount on the GL4 Pro is a significant point of failure. It suffers from inconsistent tolerances, leading to either being too tight or too loose on various rails, which can result in the unit not holding zero under recoil, especially when mounted loosely.
