Line SI Bushmaster Hammer Adjustment

[Toestr]

I have a Bushmaster with an adjustable hammer, but it has a slot in the adjuster instead of a hex key cutout. Is it supposed to use a specific adjustment tool, or just a flathead screwdriver? I haven't been able to find a flathead screwdriver that fits yet.

I believe that requires a small piece on the end of a hex wrench, I think phantoms have the same thing?

I want to say, I've never seen a specific tool. Screwdriver is probably the way to go.

All my screwdrivers aren't wide enough to get both sides of the slot.
