Designed for use with the 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.
Used with any Glock magazine, as well as Para, SVI, STI mags, BHP, Beretta, etc... and some are using it to clean AR mags as well. The hardened steel punch will last.
