Sako ARG 40 Gas piston series is based on the short-stroke gas-piston system. It makes the rifle more robust in arctic, undersea and muddy environments. The bolt carrier group also remains cooler and cleaner during firing, enabling prolonged firing sequences in adverse conditions. The piston system is also more suppressor friendly, enabling less gas blowback to the operator.
