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.
Claims11
A firing assembly for a firearm, the assembly comprising:
- a bolt carrier having a longitudinal axis, a surface defining a gas port, an inner chamber;
- the inner chamber configured to be in fluid communication with a gas block via a gas conduit;
- a surface of the firing assembly defining a valve housing, the valve housing intersecting the gas conduit;
- a valve core having an outer surface immediately adjacent the valve housing;
- the valve core configured to rotate within the valve housing;
- the valve core having a first lateral end larger in diameter than the valve housing;
- a sealing member pressed between the first lateral end of the valve core and the valve housing;
- the valve core comprising a valve port surface which selectively controls gas flow thorough the gas conduit;
- a second lateral end of the valve core comprises a radially protruding component;
- and
- wherein the protruding component of the valve core contacts a surface of the bolt carrier to bias the sealing member against the valve housing.
