SPECIFICATIONS

This rifle is designed to deliver less than 12-foot pounds of power to stay within UK law. However, FPS depends on the pellet weight and quality, i.e. brand used. Each rifle will perform differently, so we recommend trying different brands of pellets to see what works best in your new air rifle.
