It is normal as long as the angle is slight. The reason has to do with the way they have to align the crystal with the diode for maximum output if I understood correctly. My X-105 is at a slight angle but I don't really notice it when I am pointing it at things.
How many degrees are we talking? Its normal for a little bit of a slant. The collimating lens sits on an aluminum plate, and it needs to be perfectly centered with the output to get a straight beam. Usually th elens is off center just a tiny bit so the beam gets a little deflected. If the problem is really bad, they may have messed up in which case you'll have to remove and reattach/realign the lens (or get your warranty to do it for you)
