Stoeger AIRGUNS ProAdaptive Checkering is the first technical result of our “Human Tech Design” philosophy. It is the most versatile, efficient and progressive checkering developed so far, one of a kind. It is the result of a project which let shooters expose themselves to a new experience, become one with the airgun and find a perfect feeling with it. The special checkering progression actively and comfortably “fits” the gun, no matter the environment shooters find themselves in.
