I asked about this before and obviously it's not allowed since it would create a third pretty pointless category. If you do skip the reaction time and bomb sections it wont be accepted in the "Weapons Course (No GR skip)" category.

The point of the category is to run the Weapons Course without skipping anything. If you skip things then it just turns into a normal Weapons Course run because (as Derpy said a month ago) it would make the category a bit more pointless if we did just that. I've updated the rules on the category to match but a name change could also be happening I guess
