The GTUL Pistol Magazine Cleaning Brush is designed for use with the GTUL Magazine Disassembly Tool. The handle has a metal punch which can be used to depress the retaining pin on Glock magazines. The brush is used to clean away dirt, grime, and powder residue from inside the magazine tube and other parts. A qualified gunsmith can use the punch to disassemble a Glock pistol.
Note: Works for every pistol except a Springfield XDM.
