Geissele Automatics Gas Block Punch Kit For Ar-15/Ar-10

The Geissele Automatics Gas Block Punch Kit for AR-15/AR-10 is a purpose-built tool set designed to handle one of the most stubborn tasks in modern rifle maintenance: removing and installing the 0.078\" roll pin that locks your gas tube to the gas block. Whether you're a builder swapping uppers, tuning a custom build, or simply servicing a rifle that's seen hard use, a dedicated punch kit beats improvising with whatever's in your toolbox.

Gas block pins have a reputation for seizing up, especially on rifles exposed to heat cycling and carbon fouling. Fighting a stuck pin with the wrong tools is a recipe for rounded edges, stripped pins, and frustration. Geissele built this kit specifically to address that problem—precision-engineered punches that fit the pin geometry and won't slip or cause collateral damage to your receiver or gas block.

This is straightforward gunsmithing equipment for AR builders and shooters who maintain their own rifles. If you're upgrading gas blocks, replacing a piston system, or just keeping your AR-15 or AR-10 running clean, having the right punch set in your kit makes the job faster and safer for your hardware.
