POWER ADJUSTER TOOLS & DEGASSING SLEEVE
The adjustment tool bit and knurled knobs are listed separately. The knurled knob is magnetic and works with all standard 1/4 hex screwdriver bits. It's a versatile tool with many other uses, it has a 1/4 square drive socket on the opposite side that fits a standard 1/4 drive ratchet or driver handle.
The degassing sleeve is made of aluminum and fits all versions of the Magnum Adjuster. The fourth photo shows how it mounts. The adjuster knob/guide-screw backs out to remove the striker spring, then you put the sleeve on and thread it back in to degas. Count the number of turns when you remove the knob so you don't lose your adjustment position.
