How can i make an air rifle more powerful?

To increase the power of an air rifle, you can consider upgrading components such as the piston, spring, or air cylinder for higher compression. Additionally, tuning the rifle by adjusting the preload or using high-quality pellets can enhance performance. However, ensure that any modifications comply with local laws and regulations regarding air rifles, as increasing power may classify it differently legally. Always prioritize safety and proper maintenance when making modifications.
