ABSTRACT:
A noise and recoil suppressor apparatus for high powered rifles includes a tubular body with an inner central cylindrical bore and an outer cylindrical surface. A butt end portion of the tubular body is adapted for attachment to the muzzle end portion of a high powered rifle and the body provides an opposite tip portion. An annular rib extends outwardly from the outer cylindrical surface and is positioned adjacent the butt end portion of the tubular body. A plurality of space apart latterally extending cylindrical openings extends between the bore and the outer surface of the tubular body, the first plurality of openings being spaced along the tubular body beginning at the tip portion and terminating at the annular rib. A second plurality of openings extends at an acute angle with respect to the bore axis between the bore and the outer cylindrical surface adjacent the annular rib. The second plurality of openings are positioned generally between the annular rib and the first plurality of openings. Each of the second plurality of openings provides a gas travel path from the inner bore to the outer surface thereof at an angle and with an angular velocity component which forces sound waves away from the shooter.
