A footman loop clip includes a body and a bend formed in the body such that an end of the body is inboard of the bend, the body having an aperture. A pin passes through the aperture and has a pin head on one end, and a pull feature on the other end. A spring biases the pull feature toward the body. The pull feature is biased toward the body and when the pull feature is pulled a gap is formed and increased between the pin head and the end of the body.

An accessory mounting interface for a firearm, and a related method, are disclosed. The interface has a firearm accessory, a first elongated fastener, and a second fastener rotationally mated to the first elongated fastener. The first elongated fastener has right-handed threading and is arranged through a through hole in the firearm accessory with a first end extending below first and second halves of a first slot protrusion of the firearm accessory. The second fastener has a length greater than a width, the length measured along a longitudinal axis of the second fastener, the second fastener having a plurality of straight edges. At least one of the plurality of straight edges prevents the second fastener from rotating further than a closed position when the at least one of the straight edges abuts a sidewall of an elongated slot in the firearm.

A firearm strap buckle assembly includes an inlet end portion and an outlet end portion. A main tensioner bar is medially located within the buckle assembly and having upward facing surface of a first width and a downward facing surface of a second width greater than the first width. A first supporting tensioner bar is located between the inlet end and the main tensioner bar. A second supporting tensioner bar is located between the main tensioner bar and the outlet end. A first strap path is defined where the strap is positioned downwardly of the main tensioner bar. A second strap path is defined where the strap is positioned upwardly of the main tensioner bar. Frictional forces imparted to the strap when arranged within the first strap path are greater than frictional forces imparted to the strap when arranged within the second path strap.

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.
