Geissele Gas Block Roll Pin Tool 10-225 is a specialized gunsmithing aid designed to securely hold a 0.078" diameter roll pin during installation into an AR gas block, solving a fiddly problem that trips up even experienced builders.

This gas block roll pin tool is made in the USA from hardened steel with a black finish, machined precisely enough to hold a pin this small without it slipping loose mid-installation. A small tip hole holds the pin securely, letting a builder press-fit it into the gas block cleanly before final seating with a punch, rather than trying to balance a tiny pin by hand while lining up a punch at the same time.

At just 1.6 oz, this Geissele gas block accessory is highly portable and simple to use, small enough to keep in a range bag or tool kit without adding real weight.

Key Features:

• Fits standard 0.078" diameter AR gas block roll pins
• Hardened steel construction
• Black finish
• Small tip hole securely holds the pin during installation
• Weight: approximately 1.6 oz
• Made in the USA

Knowing the correct roll pin size for gas block installation is only half the job — this tool handles the part that actually gives builders trouble.
