Description

GL4 Pro QD Lever Lock

The GL4 Pro is an incredible laser, but some users have difficulty getting the QD lever to fit on their picatinny rail. Some rails are out of spec or slightly too big/too small, resulting in a QD lever that pops off under recoil. In order to fix this problem, we've developed a solution.

The QD Lever Lock completely fixes the problem of a loose QD lever. Simply slide on the lever lock until it clips on. It is now impossible for the QD lever to come undone unless the lock is removed. Simple, inexpensive, and a complete solution to the problem that allows you to keep using your laser.

Available at Defense Distributors.

Note: the lever lock is only confirmed to be compatible on Defense Distributors GL4 Pros that are either V2 or V3 (black qd lever with no hole), not V1 (hole in qd lever). If you are confused which version you have, reach out to us.

    Works as intended and fits other models

    Posted by KL on Sep 12th 2026

    Purchased this for my GL4 pro. I also have a couple of the non-pro GL4s (discontinued - same 3 functions as the pro without an IR light), and these also fit those perfectly! Note: this does slightly interfere with the stock/brace rails on a Flux Raider, but it can be closed and deploys without issue (likely impacts laser zero when brace is closed due to pressure from the rail on this lock)

    Simple Fix

    Posted by Nathan on Oct 28th 2025

    I've been having locking issues on one of my GL4 Pros. My laser would liberate itself usually after about 10 rounds. This is a brilliantly simple fix.
