System for a delayed-opposed-piston gas action assembly. Specifically, the system is comprised of a bolt, a bolt carrier, a gas block, a bolt piston, and a vent piston. Each piston will have a corresponding piston cup that will act on the piston from the gas discharged from the round. Each piston will also have a corresponding spring to bring the piston back to its original position after the gas has dissipated from the system. During the process of the firearm being discharged, the two pistons will act on the bolt carrier, causing the casing of the round to be ejected from the firearm, and a new round to be loaded into the firearm, so that the firearm can be discharged again.
