Pneumatic air gun system to improve range and accuracy

Abstract

This invention relates to a pneumatic air gun system that enhances range and accuracy, belonging to the field of pneumatic gun technology. It includes a receiver, handle, trigger, and a firing mechanism that works in conjunction with the trigger. The receiver houses a top-rotating seat, with a barrel connected to its front end and a cylinder to its rear end. A magazine is housed inside the handle. The top-rotating seat contains a top-rotating rubber pad and an adjustment component for adjusting the tightness of the rubber pad. The cylinder has a chamber communicating with the inner cavity of the top-rotating rubber pad. A gas-cutting valve, having a rod and a head, is slidably disposed within the chamber. This invention utilizes liquid carbon dioxide to vaporize, expand, and stabilize its pressure in a two-stage gas chamber before releasing it as a gas, increasing gas pressure and improving the projectile's muzzle velocity and power cycle stability. Simultaneously, by increasing the frictional area between the projectile and the rubber pad during propulsion, a stronger top-rotating effect is achieved.

Claims
