G&G Armament’s Patented Hop-Up Chamber Design Explanation
The Importance of the Hop-Up Chamber
The Hop-Up Chamber is the core component of the Airsoft gun’s ballistic accuracy and range. G&G Armament’s latest Hop-Up Chamber launched this year is different from any other product on the market and can be used with various weights of BBs—up to 0.4g—and still achieve optimal trajectory and range.
The Concept Behind the Patented Hop-Up Chamber
The main visual design of this patented Hop-Up Chamber is pictured below:
The central graphic depicts the core parts of the patented Hop-Up Chamber. The planetary icons (Sun, Saturn, and Moon) represent the mechanisms of planetary movement. The differences of masses between each celestial body reflect the range of BB weights, while their varying orbital speeds relate to the BB rotation speeds as different masses passing through the Hop-Up Chamber.
Precision, Accuracy, and Innovation (PAI)
At the bottom of the outer ring, the P. stands for Precision. The unit associated with P is 0.019, which describes the distance in millimeters that the top-down piece moves with each dial adjustment. The core parts are meticulously designed for the extreme fine-tuning capabilities of this new Hop-Up Chamber.
A. stands for Accuracy, with 39 being the total number of dial adjustments that can be operated, granting the most accurate ballistics possible using this new system.
Lastly, the I. stands for Innovation, with 0.74 representing the total travel distance in millimeters (0.019mm x 39 dials), demonstrating the innovation of this design through very precise parts with fine-tuning features to achieve the most optimal performance.
The Meaning of PAI
The combination of the three initials is PAI, similarly to the circumference ratio, Pi (π). π not only best describes the round shape of BBs, but also best describes the concepts and functions of this patent.
Achieve the Best Performance with G&G BBs
Only perfect roundness with 5.95mm diameter BB pellets paired with PAI patented Hop-Up Chamber can achieve the best range and accuracy. Choose G&G high-quality BBs for the optimal performance.
The Hop-Up System in Airsoft Guns
The Hop-Up system in airsoft guns is a design that gives BB pellets an “upward spin” when fired. By creating spin and friction with the air, it generates a small amount of lift, delaying the pellet’s drop, which results in longer range and a straighter trajectory.
🌀 Principle of Hop-Up
- Backspin effect: When fired, the BB pellet is rubbed by a rubber nub, producing upward rotation.
- Lift generation: Once spinning, the airflow above and below the pellet differs, this produces slight lift.
- Delayed drop: Although a BB pellet weighs only about 0.2g, this lift is enough to make it fly farther and straighter.
- Adjustability: Most airsoft guns have adjustable Hop-Up, ideally tuned so the trajectory is close to a straight line.
⚙️ Effects of Hop-Up
- Extended range: Effectively increases the flight distance of BB pellets.
- Improved accuracy: Reduces trajectory drop, enhancing hit probability.
- Weight differences: Lighter pellets are more affected by Hop-Up, while heavier pellets show less effect.
- Excessive backspin: If adjusted too strongly, the trajectory will curve upward, reducing accuracy.
