FX Panthera foster nipple thread type?

Anyone know what threads the foster fitting is on the FX Dynamic?
I put on a Kraford and Lypt rail and want to extend my fill fitting out for easier filling.

and the ones that fx includes arent long enough for the factory trigger guard,

but i noticed on my impact m3,
after i put on the K&L trigger guard/rail the included one worked fine,
but only because the area to the rear of the foster is machined away,
leaving a way to reach my finger in and unlock the foster.

so if the one for the panthera has the same type of cutout it should work similarly.
