Gas block fixture w/ roll pin starter punch - Precision Reflex Gas Block Fixture w/Roll Pin Starter Punch

The Precision Reflex Gas Block Fixture w/ Roll Pin Starter Punch is a great tool kit. It makes hammering in the roll pin so much easier. I use the fixture to hold the gas block in place, use my Geissele gas block roll pin tool and gas block pin punch set to hammer the roll pin into the gas block. I've used this method of installation on a bunch of upper builds. I can't emphasize enough how helpful it is to have the fixture to hold the gas block in place. Its even great for removing gas tube roll pins as they fall in one of the holes so they don't run away on you. I highly recommend it and its definitely worth every penny.
