Extended length Hex drive screwdriver bit to remove OEM slotted gas jet from FN-SCAR rifles.
The OEM gas jets are slotted, and since they are drilled for the jetting, there is little metal left for the screwdriver to grab. The best bet to get a jet out is to use a screwdriver that fits fully and tightly in the slot. Further, they need to have an extended tip, to clear in through the top of the gas cylinder.
These 4mm extended screwdriver tips are sized correctly for the M5 gas jet screw.
