The defender was a regular for the Honest Men in the Second Division and returns to Somerset Park on Sunday afternoon as Ally McCoist's side look to continue their stunning start to the SPFL League One campaign.
"You can't buy the experience you get going out on loan with a first team," McAusland told rangers.co.uk.
"It was a really good experience for me and I've benefited from it this season.
"I spoke to Mark Roberts a few times and his assistant manager Davie White stays in the same place I stay.
"I also spoke to Anthony Marenghi and Adam Hunter who were at Rangers and are now at Ayr.
"They said it was a good club and it would be good for me to go down there and play.
"As I said it's definitely helped me.
"I've kept in touch with a few of the boys and Ayr have strengthened in a few areas so it should be a good game on Sunday."
