Abstract

In compressed gas firearms, an extension with a coaxial bore is provided at the end of the barrel bore, the discharge diameter e of the coaxial bore being approximately 3-5 times the diameter d of the barrel bore. The extension can be incorporated in the barrel or can be fitted in the form of a sleeve on the barrel in coaxial relationship. With suitable dimensioning of the extension, the hit pattern of compressed gas firearms of any technical design configuration is changed for the better. Various internal shapes for the coaxial bore are specified: it may include a cylindrical section 70b and/or a section 71 which enlarges conically towards the discharge mouth.
