An air-soft gun includes a grip; a high-pressure air canister disposed in the grip; and a remaining compressed air release device including a channel member threadedly secured to an end of the air canister and including an axial channel and a sealing ring; a rotatable cap releasably secured to the channel member; a biasing member fastened between the cap and the channel member; a striker including a needle on a first end, an internal passageway, an inlet proximate the needle and communicating with the passageway, an outlet proximate a second end and communicating with the passageway, internal threads on the passageway proximate the second end, and a threaded fastener driven through the cap into the internal threads to secure the cap to the striker. The inlet is blocked by the sealing ring in an inoperative position.

A crossbow trigger assembly with a nock sensor enabling the catch to release the crossbow string only when a nock of an arrow is properly engaging the crossbow string. The trigger assembly also contains a bypass feature for deactivating the nock sensor to cause release of the crossbow string from the catch when a user activates a release switch. The bypass feature can only be activated when retractable hooks are positioned to receive the crossbow string near the catch, thereby preventing a dry fire of the crossbow string.

Systems and methods for controlling a firearm. Components embedded in a portion of the firearm enable the firearm to determine if a user of the firearm is authorized to do so, and either enable or disable a firing mechanism of the firearm accordingly. The firearm may also send communication signals regarding the status of the firearm or events detected by the firearm to a remote device controlled by an authorized user. The system may thereby notify the authorized user of attempted unauthorized use of the firearm, that the firearm has been left behind by the authorized user, or that the firearm is being tampered with. The system may also include multi-tag or a voice-override features that prevent the firearm from being used against the authorized user should the authorized user lose control of the firearm.

A safety selector for switching a firearm between at least two firing modes. The safety selector includes a cavity for placing a vial of tritium to provide a visual indication of the selected firing mode. A lock member extends through a portion of the firearm to regulate movement of a firing mechanism. A lever arm and a faceplate are connected to one end of the lock member to rotate the lock member between positions and an endcap is connected to the opposite end of the lock member to rotate therewith. At least one of the lever arm, the faceplate, and the endcap define the cavity for nesting the tritium vial. Another lever arm and faceplate may be located on the other side of the lock member for ambidextrous usage. The additional lever arm and/or faceplate may also include a cavity for nesting another tritium vial.

Exemplary embodiments include a completely redesigned fire control group to allow the safety to be engaged at any time. This unique feature can reduce or eliminate the possibility of accidental discharges of the weapon system, as engaging the safety will not allow the hammer to move forward even in the event of a malfunction.

A safety selector lever, including at least some of a lever element having a head portion and an extension portion, the extension portion includes an extension portion top wall, two extension portion sidewalls, and an extension portion bottom wall, a visual element recess is formed through at least a portion of the extension portion, at least a primary viewing aperture extends from the extension portion top wall to at least a portion of the visual element recess, and a securing screw aperture extends from the extension portion bottom wall to the visual element recess; a visual element is at least partially positionable within the visual element recess; and a securing screw is rotatably engageable within at least a portion of the securing screw aperture, such that a terminal end of the securing screw extends to contact at least a portion of the visual element within the visual element recess.

Systems, methods and devices described herein relate, generally, to controlling use of a consumable with a user device. In one embodiment, a consumable item is stored in a cartridge and when the cartridge is coupled to a user device, operation of the user device with cartridge is verified with the assistance of an external system for managing registration information. If verified, operation of the user device and cartridge is enabled and the item within the cartridge is available to be consumed by the system formed by the user device and cartridge.

Embodiments of safety selectors are disclosed. A safety selector can include a body configured to engage an internal safety mechanisms of a firearm. The safety selector can further include a first arm and a second arm that extend from the body. The first arm and the second arm can be oriented such that a non-zero angle exists between a first axis associated with the first arm and a second axis associated with the second arm.
