关于

4.5mm/ .177 The 4.5mm pellet gun caliber, also known as the .177 caliber, is one of the most popular and widely used sizes in the world of airguns. This small but effective caliber is favored for target shooting, plinking, and pest control due to its high accuracy and flat trajectory. The lightweight pellets, typically made of lead or alloy, can be shot at higher velocities compared to larger calibers, making the 4.5mm a favorite choice for competitions, especially in air rifle events where precision is key.
