Rangers opened the game with some lively attacking moves, the best chance coming in the third minute when Kevin Gallen headed just wide.
However, the London side were quickly undone by a neat counter-attack.
Danny Allsopp stormed past Rangers' defender Danny Shittu to cross the ball to unmarked Paul Heffernan, who blasted the ball past Rhys Evans to give County a 1-0 lead after only five minutes.
The lively encounter continued with some end-to-end action with both sides going just wide of the mark and County hitting the woodwork before they went 2-0 up in the 35th minute.
Richard Liburd's cross by-passed a hesitant Rangers' defence allowing former QPR player Ian Barraclough to score from close range.
Rangers had a chance to claw a goal back just before half-time thanks to an excellent move by Jerome Thomas. Thomas stormed past three defenders to create an inch-perfect pass to Foley, whose shot looped just wide of the post.
QPR had a lively start to the second half with Thomas again looking dangerous.
Rangers continued to attack and their reward came in the 62nd minute after an intense period of QPR pressure.
A loose ball was collected by Shittu outside the penalty area and he linked up with Matthew Rose who headed in from close range to level the scores.
So Notts so carelessly chucking away a two nil advantage. it seems confidence is a huge ingredient to fight against relegation. The confidence in the Notts team would have most certainly suffered a punch, with the Magpies only keeping out of the bottom four due to goal difference. The Pies are right back in this scrap. and my verdict is it will go down to the last game.
