Does anyone know what exactly the gas tube 'piece' on the TM AUG actually does? I've noticed that it has a tendency to twist and fall right off at the most inopportune moments. I don't really want to lose it out on the field, so I was thinking of just putting it aside. However, I'm wondering if there are any detrimental effects on the gun if I simply leave it off?
If you guys aren't sure what piece I'm talking about, I've circled it in the picture below:
Any ideas?
