I was looking at the schematics for it and I was wondering what the gas tube was for, at first I thought that gases passed through it to aid in cycling the bolt, but after looking some more I notice there's a plug and the end of the tube at the front end where it goes in the front sight assembly. Now I'm confused. Can anyone clarify the use of the gas tube.
