4.1.1 unlocking of bolt; extraction & ejection
1. The gas pressure generated by the burning powder in the cartridge, propels the bullet through the bore of the barrel.
2. When the bullet passes the gas port in the barrel a portion of the gas flows up into the gas block and into the gas valve.
3. The gas travels through the port in the adjustable gas valve and drives the pushrod rearward.
4. The pushrod then pushes the bolt carrier assembly to the rear.
5. as the bolt carrier moves rearward the cam pin allows the bolt to rotate to the right and unlock from the barrel
extension.
