Product Overview
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.
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.
