The "120" in the name often refers to the specific rifling configuration or a twist rate optimized for consistent pellet flight.

By reducing internal friction, the pellet can achieve more consistent velocities, which is critical for grouping at distances beyond 50 metres.

Most models range between 60 cm and 70 cm , a length typically favored for maximizing muzzle velocity and long-range stability.

Typically available in .177 (4.5mm) , the standard for competitive target shooting and small-game hunting.

Many of these barrels are sold after being pre-tested for accuracy to ensure they meet the standards required by serious airgun enthusiasts. Performance and Pricing
