Abstract
An integrally suppressed barrel in one embodiment includes a rear barrel portion defining an axial projectile bore and forwardly extending sleeve affixed to thereto. The sleeve includes vertically stacked tubular upper and lower longitudinal chambers holding a complementary configured horizontal stack of sound suppression baffles. The chambers are in fluid communication via a waist, which may be smaller in width than the chambers. A rod extending from a front end cap on the sleeve to and threadably the rear barrel secures the baffles inside the sleeve. The stack of baffles is removable from the sleeve as a self-supporting unit in one embodiment. The baffles may include upper and lower chambers which are in fluid communication to provide additional volume for gas expansion and sound suppression. The upper chambers include an asymmetrically shaped flow cone configured to direct gas from the upper to lower chambers.
