Geissele Gas Block Pin Punch Set 15-172

Geissele Gas Block Pin Punch Set 15-172 allows users to easily install or remove gas blocks on AR15/AR10 platforms, particularly useful when dealing with gas tube roll pins that are old, stuck, or rusted.

This Geissele gas block punch set includes two punches, both machined from properly hardened and tempered O1 tool steel rather than a softer, cheaper alloy that would deform or mushroom after a handful of stubborn pins. That toughness matters most on the pins that actually give builders trouble — the ones that have been in place for years and don't want to move.

Like all pin punches, this set is considered a consumable item that will eventually wear out and need replacement, which is true of any quality punch set subjected to repeated impact against hardened steel roll pins. Knowing the correct roll pin size for gas block work is only half the job — driving a stuck pin out cleanly without marring the gas block is where a proper punch set earns its keep.

Key Features:

• Two-punch set for gas block roll pin installation and removal
• Machined from hardened and tempered O1 tool steel
• Works on AR15 and AR10 platforms
• Effective on old, stuck, or rusted roll pins
• Consumable item, expected to wear with repeated use
• Precision fit for common gas block roll pin sizes
• Compact, portable tool profile
• Made in the USA

This punch set handles the half of gas block pin work that a pin-holding tool alone can't — actually driving the pin in or out without damaging the block.
