The Gers boss was speaking to reporters after the 1-1 draw at Falkirk
Despite saying it was a point gained at a tough stadium, McDowall did admit two areas of frustration in particular, first of all singling out the manner in which Rangers conceded.
The Gers boss says his squad discussed preventing crosses coming in from wide areas before the game yet that was exactly where the Scottish Championsip side fell foul at Falkirk.
And McDowall acknowledges his side were forced to pay the penalty for a basic error.
"We spoke before the game about stopping crossing coming from wide areas because after watching them we knew it was something that they do very well. We failed to do that and we ultimately paid the penalty," he said.
Meanwhile, the Rangers boss was also concerned with his side's inability to trouble hosts Falkirk in the final third.
The 51-year-old feels the Gers have improved in front of goal in recent games but says none of that was on show on Firday night.
"It was disappointing we didn’t trouble their keeper more after the last couple of games when we’ve been doing much better in the final third.
"Tonight I just felt we weren’t as sharp and the final ball wasn’t as good as it might have been," McDowall is quoted as saying by the Scottish Daily Mail.
Rangers remain third in the Scottish Championship thanks to their 1-1 draw, having missed the opportunity to leapfrog Hibernian back into second place.
McDowall's men do still have two games in hand over Hibs, however, and travel to Cowdenbeath for their next league clash.
