The Geissele Gas Block Pin Punch Set is made specifically for the removal and installation of the 0.078″ roll pin that secures the gas tube to the gas block of an AR-15/AR-10. Removal of a rusted-in gas block roll pin has always been a challenge since there are no commercial pin punches in 0.078″ diameter, and 1/16″ (0.062″) punches have a tendency to bend with very few starter punches available in that diameter.
The set includes a Starter Punch with a long, tapered end that is much more resistant to bending and buckling than the straight shank of the Pin Punch. Use the Starter Punch to get the roll pin moving, then use the Pin Punch to drive the roll pin out completely. The Geissele Gas Block Pin Punch Set is made from properly hardened and tempered 01 tool steel.
The Gas Block Pin Punch Set is considered a consumable item that will eventually wear out and will need to be replaced; Geissele will not replace tools damaged from misuse or normal wear and tear. A must-have gunsmithing tool for AR-15 and AR-10 builders and armorers who demand precision and reliability in every installation.
