Abstract: A firearm suppressor that includes a mount configured to connect the firearm suppressor to a barrel of a firearm. The firearm suppressor includes a first module connected to the mount. The interior of the first module is a first chamber and the first module does not include a baffle. The firearm suppressor includes a second module connected to the first module. The second module includes a plurality of baffles and at least one peripheral pathway that bypasses a second baffle of the plurality of baffles by fluidly connecting an exterior of a first baffle of the plurality of baffles with an exterior of an exterior of a third baffle of the plurality of baffles. The firearm suppressor includes an end cap connected to the second module.

Abstract: Disclosed herein is a modified rifle bolt carrier allowing a selectively openable vent/valve at the location where exhaust gas is pressurizing the bolt carrier to control carrier speed under suppressed fire in a first valve position or unsuppressed fire in a second valve position. A valve core is disclosed which may be rotated 180° to a first “open” setting for non-suppressed fire from its position in a “closed” position for suppressed fire, and a third “median” position. The modified bolt carrier will allow an operator of the firearm to adjust for a suppressor without changing the gas block or having to modify or adapt the front end or barrel end of the firearm.
