Bullrushing a Grappled or Grappling Opponent

[lex_dm]

I know this is sort of an old question...

Here's the info:

We have a Magus being grappled by a crustacean, in a silenced lock.

He will not be able to break free but has a Ring of the Ram on his hand. Can he use it against the grappling opponent OR on himself to break free?

How would you interpret this?

Thanks.

There are no rules that cover external forces acting on a grappled creature. Ask your GM.
