GAS BLOCK PUNCH KIT FOR AR-15/AR-308 Reviews & Ratings

GEISSELE AUTOMATICS LLC GAS BLOCK PUNCH KIT FOR AR-15/AR-308

The Geissele Automatics® Gas Block Punch Kit is purpose-built for the removal and installation of the 0.078" (1.98mm) gas tube roll pin found on AR-15 and AR-308 rifles. Gas block roll pins can be notoriously difficult to remove, especially when corrosion, carbon buildup, or tight tolerances are involved. This specialized punch kit is designed to simplify the process while reducing the risk of bent punches and damaged components.

The kit includes dedicated punches engineered specifically for gas block work. The Starter Punch features a long tapered shaft that provides superior strength and resistance to bending compared to standard punches, making it ideal for breaking stubborn roll pins loose. Once the pin is moving, the Pin Punch is used to drive the roll pin completely out. Manufactured from properly hardened and tempered O1 tool steel, the punches are built to withstand demanding firearm maintenance and armorer work.

Will it work? Yes. Will they last? NO.

Dont be fooled by the Geissele brand on these gas block punches. Bent one on the first use and Ive installed quite a few gas blocks etc with other punches etc. The good part is they were sized correctly and it did work to install the block...but... I think there are better options out there.

ok for removing roll pins not installing

these are both flat ended punches not roll pin punches. I was able to easily remove the roll pin that I was installing after it became mushroomed and deformed and was unusable. I assumed that a gas block punch kit would have a roll pin punch this was an incorrect assumption but one that set my build back because now I have to get a new roll pin and a proper roll pin punch event though I already bought an expensive gas block punch kit. If you are looking to remove a pin this is good but if you need to install one get a proper roll pin punch set.
