@valleyforge Personally I don't like how dirty a gas-delay system is. It taps gas at too high a pressure, so it drops more carbon as it cools than gas tapped close to a muzzle of a rifle. In HK P7 this problem was masked by how soon it became intolerably hot, so nobody could shoot it enough to get it jammed. I hope it's an overblown concern for the sake of Laugo Alien.
