A modular system for hunting rifles comprises barrels (13) of different caliber which can be attached via a barrel-mounted positioning rail (19) to a respective mounting tongue (11) of a stock which represents the basic unit. The stock can be constructed as long or short repeating rifle or as single-shot rifle so that any combinations of calibers and weapon types can be assembled. At its end, the barrel has a locking bush with locking lugs which cooperate with complementary locking lugs of an exchangeable bolt head (47). A longitudinal guidance system for the breech may be accommodated outside the breech area below the barrel, especially between positioning rail (19) and mounting tongue (11) to thereby attain a short overall length of the weapon. Also, through providing the locking bush with a downwardly directed cutout (53) which allows the passage of the projectile nose of a cartridge, the overall length can be further reduced.
Firearm having a stock, an exchangeable barrel and a cylinder breech including a breechblock, with a coupling element arranged at the barrel underside and a coupling element arranged at the stock of the firearm and cooperating with the coupling element of the barrel for allowing detachably mounting of the barrel to the stock, and with guide means for guiding the breech block, characterized in that the coupling element of the barrel is a positioning rail (19) which parallels the barrel (13) and has a rearward part fixedly secured to the barrel (13) in the area of the cartridge chamber (15) and a forward part extending without contacting the barrel, that the coupling element of the stock is a mounting tongue (11) which extends over the length of the positioning rail (19) and includes at least at its forward and rearward ends fastening elements which interlock with the positioning rail (19), and that the guide means (63, 65, 67) for the breechblock (43) is arranged below the barrel (13) in the area of the mounting tongue (11).
