Abstract
An integrally suppressed firearm in one embodiment includes a rear firing portion defining an axial projectile bore and front suppressor portion. The suppressor portion includes a longitudinal stack of sound suppression baffles each defining a gas expansion chamber in fluid communication with the projectile bore. A mounting rod extends rearward from a front end cap of the suppressor portion and threadably engages a mounting adapter that removably couples the suppressor portion to the firing portion. A muzzle cap disposed inside a rearmost baffle removably couples the mounting adapter to the firing portion. When tightened, the rod axially compresses the baffle stack and forms a combustion gas tight enclosure without need for an additional external pressure retention tube or sleeve. The baffles are configured to form a press-fit frictional interlock with each other such that the baffle stack is self-supporting. An optional accessory rail may be coupled to the adapter.
