Negative Airsoft does a detailed technical demonstration of installing the Perun V2 Lightning MOSFET into an AEG. He begins by unboxing the unit, showcasing its compact design and the included wiring harness, while subtly warning viewers that if they aren't comfortable seeing a gearbox in pieces, they might want to look away.

Negative Airsoft features a high rate of fire Dual Sector Gear (DSG) airsoft build, primarily to prove he can do it despite what internet skeptics might say. He tears down the gearbox to demonstrate that, after several hundred test rounds, the internals show zero wear and tear. The build includes custom modifications like a tapered piston and a unique wiring setup to fit batteries into the rear stock, all while maintaining a consistent power output.

Negative Airsoft demonstrates how to install the F-Bomb hop rubber into various airsoft barrels and hop-up units. He shows that the process involves lining up the ridge of the rubber with the barrel's groove and carefully sliding it into the hop-up unit. He emphasizes that this component is compatible with a wide range of brands, from standard factory parts to custom setups, and notes that grease should be avoided during installation as it is counterproductive to the rubber's function.

Negative Airsoft approaches the Lambda/Raptor SR-2M with a mix of curiosity and skepticism, noting that previous feedback on the model has been polarized between high praise and total failure. Upon first handling the replica, he questions the ergonomics of the folding stock, suggesting that resting one’s face on it would be an unpleasant experience. The overall aesthetic is compared to a low-effort version of other common models, and the lightweight magazine immediately raises eyebrows.

Luke from Negative Airsoft took a deep dive into an ASG B&T APC 556 that arrived with a "brand new" label but a suspicious internal history. While the exterior looked pristine, the guts of the machine told a different story involving questionable tape, decimated pads, and mystery shims that certainly didn't come from the factory.

Negative Airsoft gives a blunt assessment of a KWA airsoft rifle that arrived in a state of mechanical despair. The initial inspection reveals a collection of questionable life choices, including mixed ammunition weights and a gearbox that sounds more like a blender full of gravel than a precision instrument.

Negative Airsoft takes a break from the workbench to vent about various manufacturers while enjoying a beverage in bed. The video serves as a guide to which brands are actually building their own gear and which ones are simply paying for fancy stickers and trademarks to slap on someone else's homework. It's an honest look at the "wormhole" of rebranding that often leaves enthusiasts paying a premium for a name rather than improved performance.

Luke from Negative Airsoft tackles a trio of airsoft replicas that seem to have "walked into a bar" and emerged with varying degrees of mechanical trauma. The journey begins with a G&P AEG that arrived in a box shaped vaguely like a rifle but held together mostly by hope and bubble wrap.

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.

Negative Airsoft demonstrates a satirical "pro upgrade" for an airsoft gun by heavily wrapping the internal components in PTFE tape. He features a tight-bore barrel and a hop-up unit completely covered in layers of the sealant, mockingly suggesting that the material is a universal solution for performance issues.
