The indirect-acting powder-actuated fastening tool includes a barrel and a barrel breech adjustably screwed together and telescopically carried by a slide assembly which, in turn, is telescopically carried by the tool receiver. The slide assembly and the barrel are operably connected for corotation. Rotation of the slide assembly produces a joint axial displacement of the barrel and the slide assembly relative to the barrel breech to vary the initial vol. The axial relation between the slide assembly and the barrel is thus preserved during power level adjustment to effect angle-fire control.
