Precision Reflex Gas Block Assembly Fixture with Roll Pin Starter

The Precision Reflex Gas Block Assembly Fixture with Roll Pin Starter (brand part no. 05-100) is built by Precision Reflex to hold a gas block square and steady while its retaining roll pins are started and driven. Gas blocks are small and easy to shift out of alignment when a punch is applied freehand, and a misaligned block can bind the gas system or cant the front sight base; this fixture locates the block correctly and includes a built-in roll pin starter to get the pin square before final driving. It’s a bench accessory built for AR-platform gas block installation and gunsmithing work.
