The Light Blues saw their 100 per cent Scottish League One record finally come to an end when they were held to a last-gasp 1-1 draw on Boxing Day.
Rangers now face closest challengers - and fellow full-timers - Dunfermline at East End Park as they aim to steer their season back on track.
The last meeting between the two sides proved to be a bruising encounter for the Glasgow giants, with several players needing hospital treatment and McCulloch himself requiring stitches in a head wound.
But the Gers captain is relishing the prospect of what could be their biggest challenge so far this term.
McCulloch said: "That's the way their manager has always set his teams up - physical, but fair.
"They're a good team and have got some good players so it is going to be tough.
"But I don't think we could have picked a better place to play coming off the back of the Stranraer game."
The Ibrox utility man insists Rangers have no option but to bounce back quickly from the disappointment against Stranraer when they travel to Fife on Monday night.
He said: "I thought in the second half against Stranraer we let ourselves down.
"We weren't at our best in the first half, but we got our goal.
"Usually we go on to kill the game in the second half by getting two, three or four, but the players on the pitch let the management and the fans down.
"But the positives are that at least we have got a chance to bounce back on Monday in what is quite a big game for us.
"When you play at this club you need to bounce back. We don't have to wait too long for the next game, so we'll be looking forward to Monday night to get a chance to put things right."
He added: "I think it had been 19 days since our last game. Then again, we should still have been winning that game.
"We were bit rusty. Maybe mentality-wise we were a wee bit lazy.
"With the Christmas period, you look for every excuse under the sun, but the boys on the pitch should be doing a lot better, myself included."
