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. Additionally, 1/16" (0.062") punches have a tendency to bend and very few starter punches are available in 1/16" diameter.
The Geissele Gas Block Pin Punch Set makes gas block work a whole lot easier. The first punch to grab when removing the roll pin is the Starter Punch. This is the punch with the long, tapered end. The long taper 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, meaning they will eventually wear out and will need to be replaced. Geissele will not replace tools damaged from misuse or normal wear and tear. Always make sure your weapon is unloaded and the magazine removed before starting work.
