1. An indirect gas operating system for a semi-automatic or automatic rifle, the indirect gas operating system comprising:
- a sleeve removably secured to a forward end of a gas block of the rifle;
a piston slidably received within the gas block, wherein the gas block and the sleeve fluidly couple the piston to a bore of a barrel of the rifle;
wherein an increase in pressure in the bore of the rifle causes the piston to move away from the sleeve; and
wherein the sleeve and the piston are each capable of being removed from the rifle through the forward end of the gas block.

15. A method of indirectly coupling a barrel of a semi-automatic or automatic rifle to a bolt carrier of the rifle, comprising:
-
fluidly coupling a piston to a bore of a barrel of the rifle, the piston being slidably received within a gas block of the rifle; removably securing a sleeve to a forward end of the gas block of the rifle, wherein the gas block and the sleeve fluidly couple the piston to the bore of the barrel of the rifle; and coupling an operating rod to the piston, wherein an increase in pressure in the bore of the rifle causes the piston to move away from the sleeve and movement of the piston away from the sleeve causes movement of the operating rod and wherein the sleeve and the piston are each capable of being removed from the rifle through the forward end of the gas block. - View Dependent Claims (16, 17, 18, 19, 20)
