An existing rotating bolt operation but with a fluted chamber and no gas piston. This allows gas to not only lubricate the round but floods the chamber past the locking lugs to the bolt carrier with a head that acts as a gas piston. This would save drilling holes in the barrel to install gas pistons and make gas operation simple and near to that of blowback operation. This operation uses the fluted chamber as a gas port and the bolt carrier acts as a piston head.
