The invention relates to a projectile weapon with a rotary bolt and rifled barrel that is powered by an elastic device and/or compressed gas, and comprises a housing with an upper surface and a groove in the upper surface for the movement of the bolt. The novelty lies in the bolt being a rotary bolt with a rifled profile which comprises a bolt body and sleeve connected to it by a bearing, and a bracket attaches a rifled barrel with a rifled cross section and an friction surface to the front part of the housing, whereas the rifled profile of the rotary bolt corresponds to the pitch and cross section of the rifled barrel, whereas the friction surfaces of the rifled profiles are made of a material with low friction coefficient. The projectile weapon may be implemented in the form of a crossbow or a bow. Leiutis käsitleb vintnoole ja vinttoruga laskerelva, mis töötab elastse vahendi ja/või surugaasi jõul ja sisaldab laskerelva korpust, millel on ülemine pind ja pikisuunaline juhttee ülemisel pinnal noole liikumiseks. Uudne on see, et nooleks on hõõrdepinnaga vintprofiiliga vintnool, millel on noolekeha ja sellega laagerduse teel ühendatud puks, ja laskerelva korpuse esiossa on kronsteini abil kinnitatud hõõrdepinnaga vintprofiiliga vinttoru, kusjuures vintnoole vintprofiil on vastavuses vinttoru vintprofiili sammu ja ristlõikega, kusjuures vintprofiilide pinnad ja hõõrdepinnad on väikese hõõrdeteguriga materjalist. Laskerelv võib olla amb või vibu.
