The striker spent only eight months at Ibrox, scoring a handful of goals in an injury-hit spell that saw his career stall rather than kick-start.
This weekend, he will come up against Ally McCoist's side for the first time since his departure in March, a mutually agreed exit that left both parties unfulfilled.
The 32-year-old is in the same mould as Jon Daly, the man who currently leads the Light Blue attack and scored four times in the 8-0 rout of Stenhousemuir last weekend.
But while the former Dundee United striker is starring for McCoist's side as Rangers bid to make their way up through the leagues, Kyle has had to give up his dreams of his own top-flight return to prove his worth after a frustrating and short-lived Ibrox career.
"I was confident going into Rangers that I could do well there," he told SportTimes. "I worked hard and got myself in the team and then I scored some goals.
"I scored three times in the four starts I made. But then I got injured and ended up missing the end of the season.
"Had I got back in the time frame that I should have got back in, then there would still have been a few months left of the season to try and get another deal. Circumstances dictated that didn't happen.
"I have no hard feelings, sometimes these things happen in football. Not everything goes right. If I had kept fit, kept scoring goals and done the business, it might have been me that was scoring four goals on Saturday instead of Jon Daly. That is football, it is all hindsight."
Kyle was not the only signing that didn't work out for Rangers last term. Many of the players who followed him in to Ibrox also failed to make an impact.
McCoist overhauled his squad with the capture of nine new stars during the close season, with the results hugely impressive for the Gers so far as they have raced away at the top of the League One standings.
A trip to Somerset Park on Sunday is their next stop on the road back to the summit of Scottish football and Kyle reckons the Light Blues are well equipped for the challenges ahead.
"They have signed nine new players and that has made the the players work harder to make sure they stay in the team," he said.
"If they don't perform, they will get dropped and someone else will come in in their place. The spine of the team is really strong. Lee McCulloch has been there for years and knows the ins and outs of the club, he brings massive experience to the team and squad.
"I played with Cammy Bell at Kilmarnock and he is a very good goalkeeper. Lee Wallace is another experienced player and so is Ian Black, who the fans are starting to see the best of. Jon Daly is an SPL forward who knows where the back of the net is and how to bring people into play.
"They have got a good squad now and a good team for heading back to where they belong eventually. It is looking good for Rangers.
"The manager has got it right and they are doing what everyone expected they would do, beating teams by a few goals and playing well."
Despite their impressive start to the campaign, boss McCoist has stated his belief that there is far more to come from his side, while admitting that there is still some way to go on their journey back to where they belong.
He has assembled arguably the second strongest squad of players in Scotland and while League One success is expected, Kyle knows his former boss must look long-term, too.
He said: "Ally is not short of options, but I think he is trying to build a team for the future and get a group of players, 15 or 16, that will take them back to the top so that when they do get there, it will be the same group that has played together week in week out for a couple of years.
"You can see the manager trying to build that squad. Last year they brought players in in dribs and drabs and it didn't quite work out.
"It is all about planning ahead and trying to get a solid group. A team doesn't just form overnight."
While Rangers have set their sights on title glory, Kyle has a far different focus in the coming weeks. Mark Roberts' side are currently fourth in the standings as they bid to join the Gers in the Championship next season via the play-offs.
And Kyle hopes his Somerset Park stint will prove beneficial for all concerned.
He said: "I was hoping to get a deal with a full-time club, but it wasn't happening and I knew I had to sign at a club to get playing again.
They are helping me out and hopefully I can help them out. It works both ways. I am looking forward to the months ahead.
"For me, it is just a chance to get back on the pitch and hopefully I can do well here.
"The chance to play against Rangers this season was, of course, one of the reasons I signed for Ayr.
"It is an added bonus. If you do well against them, it gives you more of a profile.
People might look at the lower leagues and write you off, but if you can perform against Rangers you can show that you can still cut the mustard at the top of Scottish football."
