The invention relates to a rotary bolt with rollers and a projectile weapon with a rifled barrel that is powered by an elastic device and/or compressed gas, and comprises a housing with an upper surface and a longitudinal groove in the upper surface for the movement of the bolt that comprises a tip and a front part. The novelty lies in the bolt being a rotary bolt with rollers that has a friction surface and a rifled profile, the longitudinal groove is a rifled barrel with a friction surface and rifled profile, whereas at least one axle with at least one roller has been positioned into the front end of the rotary bolt, and the roller providing the rotary bolt rotary motion by rolling on the rifled profile of the rifled barrel. Leiutis käsitleb rull-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 nooleotsaga ja esiosaga noole liikumiseks. Uus on see, et nooleks on hõõrdepinnaga vintprofiiliga rull-vintnool, pikisuunaliseks juhtteeks on hõõrdepinnaga vintprofiiliga vinttoru, kusjuures rull-vintnoole esiossa on paigaldatud vähemalt üks telg koos vähemalt ühe pöörleva rulliga, mis rull-vintnoole veeremisel vinttoru vintprofiilil annab rull-vintnoolele pöörleva liikumise.
