vertical asa on milled dallara rail?

[st6212]

Anyone know if you can mount a vertail ASA on a ULE milled Dallara rail?

From the pics I've seen, it looks like the vertical ASA mounting hole has been milled out.

Do you mean the asa threaded part or the gas port? (Or neither if I've got it wrong). I have a dallara myself with a cp foregrip screwed in the usual way.
