摘要 A firearm including a barrel holder for accommodating interchangeable barrels. A breechblock housing, connected to a stock, includes in a forward zone thereof, a recess having an abutment surface for absorbing recoil forces, with the barrel including a tubular member fixedly connected to a rear end thereof and including an extension fitting into the recess. The tubular member has a relatively large axial length and extends forwardly from a locking mechanism beyond a cartridge chamber of the firearm. The extension is provided at the rear end of the tubular member, and the abutment surface has an undercut portion partially extending over the extension from above. A downwardly projecting second extension is provided at the front end of the tubular member, with the second extension including a locking bolt recess. The breechblock housing extends up to a zone of the second extension and carries, at that location, a locked bolt cooperating with the locked bolt recess.
