Abstract:
1. A device for delaying the action of a gas action operated firearm having a barrel with a bore, an action tube and a bolt block comprising: a container having a gas chamber and an outlet, wherein the outlet is in fluid communication with the action tube of the firearm; a port in fluid communication between the gas chamber and the bore of the barrel; a one-way check valve in the port, wherein the one-way check valve permits the fluid flow from the bore to the gas chamber; a gas release valve having at least an open and a closed position, disposed on the container and in fluid communication with the gas chamber and the outlet; and, linkage rotatably attached to the gas release valve and in mechanical communication with the bolt block, wherein when the gas release valve is in the closed position, gas is retained in the gas chamber and the linkage blocks the bolt block from moving, and when the gas release valve is in the open position the linkage unblocks the bolt block permitting normal gas action of the firearm.
