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.

As the demonstration continues, he removes the hop-up unit and rubber components to reveal even more tape underneath the assembly. He ends by saying that while some believe the tape can fix any mechanical problem, its excessive and improper use is actually the reason the specific gun required repairs.
