G&G Armament show their patented hop-up system designed for airsoft guns. It illustrates the internal mechanical components and the airflow path that provides backspin to the projectile. The presentation uses 3D animations to show how the hop-up rubber and tensioner interact with the BB as it travels through the inner barrel.

The system features a rotary adjustment dial that allows for precise changes to the pressure applied to the hop-up bucking. This mechanism is shown to provide stability during the firing sequence by maintaining consistent contact between the rubber nub and the BB. The design focuses on improving the flight path and range of the airsoft pellets through controlled friction.

Visual comparisons are provided to explain the difference between standard designs and this specific patented version. The video highlights the structural layout of the unit, including its housing and the way it integrates with the magazine feed lip. These technical details show how the air seal is maintained to prevent energy loss during operation.
