In a separate meeting, Mr Dickson tells the NRA that One Nation "lacks money" and lacks "people on the ground", and requests that they "point us in the right direction".
The NRA set them up with energy giant Koch Industries, a company that makes massive political donations to conservative causes.
Asked by Muller how much money they were after, the One Nation pair suggested anywhere between $10 and $20 million.
"If we get to a point where we can talk about figures, what sort of number are you guys thinking?" asked Muller.
"I'm thinking 10," said Mr Dickson.
"No, I was thinking 20," said Mr Ashby.
