The gas system is what makes an AR-15 semi-automatic. As the bullet is pressed out of the barrel by increasing gasses, a little section of that gas is funneled backwards through the gas tube. It after that pushes the bolt provider group to the back. In this carefully tuned procedure, the invested covering is ejected, the hammer is cocked, a brand-new round is pushed up from the publication, then chambered and also locked.

The gas tube itself is affordable and also uncomplicated; the essential thing is that its length matches your barrel’s system. Daniel Protection has a post going a little more extensive about the gas system.
