Sean Dyche admitted it was a "head-scratcher" that Burnley came away from Loftus Road with nothing.
The Clarets spurned several big chances - including two terrific saves from Rangers stopper Rob Green - before going down to second half goals from Leroy Fer and Charlie Austin.
And Dyche was left to rue missed chances as the Clarets four-game unbeaten run came to an end.
Dyche said: "It was a game of missed chances, that's the top and bottom of it.
"I thought the performance was good and I was reasonably happy with that.
"We created chances, particularly in the first half and early in the second and Rob Green had pulled out one of the saves of the season.
"We were right behind it and Boydy hit an absolute worldie that's going right in the top corner before he gets a fingertip to it.
"Scott then had one that hit him in the face, but fair play again to the keeper.
"But those chances are massive in the Premier League and it's hard to come back from conceding goals.
"The first one is an unlucky deflection off Ben Mee. It's a terrific tackle and weirdly I think if he doesn't Tom saves it.
"We're disappointed with the second one - and overall it's a bit of a head-scratcher because generally I was happy with the performance."
Dyche, who revealed that absent defender Stephen Ward has been diagnosed with a hairline fracture of the foot that will sideline the defender for a spell, added: "I always try to be honest and I genuinely thought that was a reasonable performance.
"In fact I thought it was better than reasonable, I felt there were more good points than in other performances, so it's tough to take.
"But that's one loss in five now and that's a big marker in the Premier League"
