Well, you would have to clear it with Zoxin first.
He stated that anyone actively talking on the forums could beta test, but I am not sure about weapons testing.
Just as a note of future reference, Weapons Testing is not just looking for glitches, it is to make sure the model+texture+animation came out right and if anything needs to be changed.
