Automatically loaded rifle with rigidly secured barrels in housing

摘要

In the fitted state at least one barrel (29) is rigidly secured in the plastics housing (1), in which are rigidly fitted a metal retaining sleeve (3) with a barrel holder (5). In addition to metal, the sleeve may be made of material similar to the metal deformation and strength. The barrel holder surrounds the barrel rear end coaxially and provides a strong abutment. Pref. in the barrel holder is located an intermediate sleeve (17) for the barrel rear end of the same material as the retaining sleeve. Typically the barrel, intermediate sleeve, or the barrel holder are screwed together.
