The Telegraph has posted an article with the photo of the rifle they believed was used. If this is indeed the rifle then it had to have been left in position and was not carried up by the shooter. Assuming the photos of the shooter walking up the stairwell, released by the FBI, are also accurate.

It doesn't look like the rifle would break down to be cartable in a backpack.

Looks like the scope would interfere with a stock military Mauser safety. Probably not much clearance for the bolt handle, either.
