Front grip mount for classic 'mag

[Surestick]

I'm looking for a front grip mount for a classic 'mag, the gas through kind with the ASA threading that will accept an expansion chamber or reg.
The only ones I can find on the AGD website attach with two bolts but my rail takes one w/one bolt.
I'm probably just blind & not seeing it (been known to happen!) but can somebody point me in the right direction?
Thanks.

Thanks! I probably saw that & ignored it due to the title - I was looking for something w/the word "grip" in it.
