An interface for coupling a bipod to a sling stud of a firearm forend. The interface can include two pawls that pivot to release or grasp the sling stud. The pawls can be biased upward via a detent that rides within a vertical aperture in a pivot holder. The pivot holder can move up and down within a vertical aperture in a mounting plate of the interface, and via this movement the pawls may be forced open or closed. A bottom surface of one or both pawls can include an irregular surface different portions of which interface with a top of the detent depending on a vertical position of the pivot holder within the aperture in the mounting plate.

Described herein is an adapter for converting a single sling mount to dual-sling mount. The adapter comprises a body having a modified “H” configuration with two opposing legs joined to two outwardly extending arms. The two opposing legs each have a transverse bore linearly aligned with one another. Each outwardly extending arm also has a transverse bore. The resulting gun sling assembly allows one to carry the gun across one's back in a backpack fashion. An adapter having a modified “Y” configuration allows one to carry a military-style gun across one's back in a backpack fashion.

A gun lock system for securing a portion of a firearm for safety and theft-deterence. wherein: the gun lock system comprises a tongue, a lock shell, and a release assembly. The lock shell comprises a width, a height, a depth, a front side, a back side, a top side, a first side, a second side and a bottom end. The lock shell further comprises a tongue slot configured to selectively receive a portion of the tongue. The tongue comprises a tongue width and a tongue depth. The tongue slot comprises a slot width and a slot depth. The tongue comprises a first end and a second end.

The buttstock assembly uses a modular design including interchangeable end attachments and sling strap connectors. The interchangeable end attachments allow the buttstock to have different toe heights and configurations for different shooting applications. The interchangeable strap connectors allow the use of either quick-disconnect style sling swivels or more traditional fixed strap loops as desired. The buttstock assembly also uses a “trigger” style locking mechanism to selectively position and lock the buttstock along the length of the extension tube to adjust the overall length of pull of the weapon.
