A blank-only machine non-firearm includes a replica shell and replica barrel from a non-firing replica machinegun, such as an airsoft replica machinegun. An insert that defines a receiver may be inserted into and contained within the interior volume of the replica shell. An exhaust gas barrel is attached to the receiver and extends within the replica barrel. The replica receiver and barrel are configured to fire blank cartridges and not to fire live rounds. Noise and flash from a firing blank cartridge is directed from a chamber defined by the receiver to the exhaust gas barrel and hence to the replica barrel.
