Pls what kind of threads are tapped under The ARCA rail of the FX Panthera on either side of the M-LOK looking slots where I am pointing to in the pic?

I am trying to mount a standard M-LOK pic rail in there and it does not fit. I do not have an ARCA attachment on my tripods. I have multiple rifles with picrails so trying to make a standard M-LOK pic rail fit in there so I can use my standard pic bipods. Also trying to keep the height to a minimum. I think some ARCA to pic adapters exists but they add some height so attaching a standard M-LOK rail may work better for me if possible.

Does anyone know if these are standard M-LOK slots ? Not sure why my M-LOK pic rail does not fit

Tnx

?

use

Answering my own question (i think) I found some M16*4 bolts lying in my garage and tried it in there and they seem to fit. Completed my install with a little blue Loctite, Somebody please correct me if I installed incorrect thread in there.

Now I just need some scope rings high enough so that my scope does not touch the barrel and I can go shooting it .. I used one of the M-Lock provided screws in the slot and one M16*4 treads inside the second tapped holes from the end.
