Which weapon is gas operated?

Gas operation uses a portion of the propellant gases from each fired round to drive the action. In a gas-operated weapon like the 240B, gas is vented from the barrel through a port into a piston system. The gas piston is pushed rearward, which cycles the bolt: it extracts the spent casing, ejects it, and then chambers the next round. This method enables smooth, sustained fire with a belt-fed system. The other weapons in the list don’t use this gas-driven cycling in the same way, so the 240B is the one that uses gas operation.
