An Anti-Replicator gun (or ARG, for short) is a weapon designed to destroy the Asurans, a form of Replicators found in the Pegasus galaxy. It was designed by Lt. Colonel Samantha Carter, based on the disruptor technology designed by Colonel Jack O'Neill using an Ancient Repository of knowledge and put into mass production by the Asgard. The ARGs, like the original Replicator disruptor, emit a directional energy pulse designed to disrupt the subspace link that allows Replicator cells to communicate, reducing the target to a harmless pile of individual cells. Unlike the original, the ARG has been scaled down into a much more compact design. It is built much like a small rifle, with the emitter placed at the end of the barrel.
