1. A rotating bolt firearm, comprising: an upper receiver;a bolt installable in the upper receiver and moveable between a first position and a second position;a barrel comprising an internal chamber operatively coupled to the upper receiver, the barrel configured to receive a forward portion of the bolt;a gas tube; andan operating system comprising: a body comprising a gas port fluidly connecting the internal chamber of the barrel to an internal chamber of the body;an adjustment comprising a threaded portion configured to engage the body, the adjustment comprising a plurality of notches extending forward out of the body, the adjustment configured to block the gas port at an interface between the gas port and the internal chamber of the body, thus preventing flow of gas from the internal chamber of the barrel into the internal chamber of the body,wherein the adjustment comprises a nipple configured to engage the gas tube at an interface between the internal chamber of the body and the gas tube and block flow of gas from the internal chamber of the body into the gas tube;a pin inserted through a side of the body, wherein the pin is configured to retain the adjustment within the internal chamber of the body; anda spring loaded detent assembly comprising a ball loaded by a spring, wherein the ball is configured to selectively engage one of the plurality of notches in response to rotating the adjustment,wherein the operating system is configured to adjustably vary a gas pressure in the operating system. 2. The rotating bolt firearm of claim 1, further comprising a retention rod located at least partially within the body, wherein the retention rod is configured to restrain movement of the adjustment. 3. The rotating bolt firearm of claim 2, further comprising a spring located within the body and contacting the retention rod. 4. The rotating bolt firearm of claim 3, wherein the retention rod is configured to compress the spring. 5. The rotating bolt firearm of claim 1, wherein the adjustment and a plug form an assembly, wherein the assembly is removable from the body. 6. The rotating bolt firearm of claim 5, wherein the assembly is retained in the body with a pin. 7. The rotating bolt firearm of claim 1, wherein the adjustment and the gas tube are coaxial. 8. The rotating bolt firearm of claim 1, wherein the adjustment and the gas tube are parallel. 9. The rotating bolt firearm of claim 1, wherein the gas tube is parallel to the barrel, and wherein the nipple is located at least partially within the gas tube. 10. The rotating bolt firearm of claim 1, wherein the adjustment inhibits flow of gas at a first location and a second location. 11. The rotating bolt firearm of claim 10, wherein the first location is the interface between the gas port and the internal chamber of the body, and wherein the second location is the interface between the internal chamber of the body and the gas tube. 12. The rotating bolt firearm of claim 1, wherein the adjustment is configured to translate parallel to the barrel. 13. The rotating bolt firearm of claim 1, wherein the adjustment is configured to be adjusted by a user grasping the notches and rotating the adjustment. 14. The rotating bolt firearm of claim 1, wherein the nipple is located within a forward end of the gas tube. 15. The rotating bolt firearm of claim 1, wherein the nipple is configured to translate parallel to the gas tube in order to block flow of gas from the internal chamber of the body to the gas tube.
