Abstract
Locking systems for use with firearms are described. An example locking system for use with a firearm includes a breechblock carrier and a lock spring mechanism that includes a piston. The breechblock carrier is configured to interaction with the piston. Additionally, the example locking system includes a first aperture. The piston is configured to expel fluid through the first aperture when the breechblock carrier retracts.
Claims28
A locking system for use with a firearm, comprising:
- a breechblock;
- a breechblock carrier;
- a lock spring mechanism including a piston, the breechblock carrier being configured to drive the piston as the breechblock carrier retracts to open a breech;
- and
- a first aperture, wherein the piston is configured to expel fluid through the first aperture to an exterior of the firearm when the breechblock carrier retracts.
A locking system for use with a firearm, comprising:
- a breechblock carrier;
- a lock spring mechanism including a piston, the breechblock carrier being configured to interact with the piston to move the piston as the breechblock carrier retracts to open a breech;
- a first aperture, wherein the piston is configured to expel fluid through the first aperture when the breechblock carrier retracts;
- a chamber that is fluidly coupled to an exterior of a firearm by the first aperture, wherein when fluid is contained in the chamber, the fluid is to flow from the chamber through the first aperture to the exterior of the firearm;
- and
- at least one notch to horizontally adjust a shoulder support relative to the firearm, wherein the first aperture is adjacent one of the at least one notch and wherein the first aperture is radially positioned relative to an axis of the firearm.

- a breechblock carrier;
- a lock spring mechanism including a piston, the breechblock carrier being configured to interact with the piston to move the piston as the breechblock carrier retracts to open a breech;
- a first aperture, wherein the piston is configured to expel fluid through the first aperture when the breechblock carrier retracts;
- a second aperture that is at least partially defined by the breechblock carrier, wherein the second aperture is radially positioned relative to an axis of a firearm;
- a chamber that is fluidly coupled to an exterior of a firearm by the second aperture, wherein when fluid is contained in the chamber, the fluid is to flow from the chamber through the second aperture to an exterior of the firearm;
- and
- a breechblock adjacent the breechblock carrier, wherein the chamber is at least partially positioned in the breechblock carrier.
A locking system for use with a firearm, comprising:
- an aperture;
- and
- a chamber that is fluidly coupled to an exterior of a firearm by the aperture, wherein when fluid is contained in the chamber, the fluid is to flow from the chamber through the aperture to the exterior of the firearm in response to a component of the firearm being driven by a breechblock carrier relative to the aperture as a breech of the firearm is opened.
