I have a feeling someone mixed that gas-tube up with a different model's gas tube. I'd return it and get another one. I wouldnt feel comfortable with that little of contact on the gas-block considering the amount of friction between the gas-piston and the gas-tube can be violent at times.
Just curious, where did you buy the gas-tube from?
I'm already surrounded by half-dead brainless people already, the zombie apocalypse would just give me a reason to be productive and get rid of them.
