GAS OPERATING SYSTEM FOR AN AUTOMATIC FIREARM

---

Abstract

---

Techniques and architectures are disclosed for a gas operating system for a firearm. The system includes a barrel having a bore including a rifled portion. Attached to the barrel is a gas block. Located distally of the rifled portion of the bore is a gas expansion chamber in fluid communication with the bore and the gas block. In some examples, the gas expansion chamber includes a diameter at least twice the bore diameter. The gas block of the gas operating system, in some examples, includes a piston, where in response to receiving gases from the gas expansion chamber, the piston cycles the gas operating system.
