Oh, they did stick with it.
On page 166, the 6E rulebook has a picture of Great Crusade Space Wolves, and this is the gun that they carry. At least it looks like it - you can't see the entire weapon, but it is a bolter with the magazine at the front, which seems fairly iconic.
Also see these miniatures:

Now, the second from the left seems like a Great Crusade era Space Marine who already carries a newer boltgun, but I'm going to assume that they switched from that Thunder Warrior's gun to the newer model sometime
during the Great Crusade - and after the Heresy, no new look was ever invented because of tech stagnation.
[edit] I suppose it does mean that the "current" bolters are also okay for Heresy Era Space Marines - they were just still "new" back then and not everyone already had them issued.
