Negative Airsoft goes over the Toxicant Sig XM5, a replica of the U.S. military's new service rifle. He checks the exterior features, noting the plethora of ambidextrous buttons and controls that seem to multiply with every glance. While the build quality is acknowledged, the review is peppered with critiques about the ergonomics, particularly the mismatched proportions of a large rifle body paired with a surprisingly small stock.

The mechanical discussion reveals that the internal system is based on the Tokyo Marui MWS, allowing it to function relatively well even in chilly weather. However, a warning is issued regarding the bolt assembly, which contains tiny, unpinned rollers that are prone to making a sudden escape during maintenance. There is also some debate over the nozzle quality and the necessity of certain aftermarket parts, though the hop-up adjustment system receives a nod for its clever design that prevents damage to the rubber.

He share anecdotes about the cost of the kit and the absurdity of certain "modern" features, such as the translucent magazine that comes with a paper insert showing fake bullets. For airsoft players, this episode serves as a technical walkthrough and a comedy routine, concluding that while the rifle is a pricey piece of equipment, it is mostly a way for airsoft players to look fashionable on the field.
