Abstract: 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.

Abstract: A method for securing an accessory to a firearm includes inserting a lug and a nut into an entry opening positioned between first and second opposite ends of a slot formed in a wall of the firearm. The lug restricts the nut from rotating about an axis of a threaded member with which the nut is in threaded engagement. The slot has a first width, the entry opening has a second width that is greater than the first width, and the nut has a major dimension that is larger than the first width and smaller than the second width. The method also includes sliding the lug and nut in the slot in a sliding direction toward the first end or the second end, and rotating the threaded member with respect to the nut to clamp the wall between a surface of the nut and a surface of the accessory.

Abstract: A handguard assembly and related method are provided. The handguard assembly can include a fastener assembly that installs in a handguard bore of a handguard. The fastener assembly can include a fastener head including first threads threaded in a first direction, a shaft extending from the fastener head, the shaft including second threads threaded in a second direction opposite the first direction, and a lock tab threadably engaging the second threads, the lock tab including a tab head. When the fastener assembly is converted from a retracted mode to an extended mode, the tab head can wedge into a barrel nut groove to secure the handguard to the barrel nut thereby impairing the handguard from rotating and/or sliding relative to the barrel nut. The shaft can thread into the lock tab when the fastener assembly is installed relative to the groove, with the overall length of the fastener assembly increasing as the tab head moves in the groove.

Abstract: A handguard attachment assembly for a firearm is disclosed. The assembly includes a handguard with an elongate structure extending between a first end and a second end, where the handguard has at least one opening proximate the first end. A flange insert is received in an opening on a first side of the handguard and engages the handguard. A fastener secures the flange insert to a connector positioned over the barrel nut. The fastener can be tightened to draw the handguard to the barrel nut. The connector can be a bridge connector positioned on or over the barrel nut within the handguard, or can be a connector with a flange portion that engages the second side of the handguard and has a connector body that extends towards the flange insert on the first side, to name a few examples.

Abstract: A modular precision rifle assembly 150 and a method for configuring rifle components allowing users to change barrel subassemblies 214 (i.e., for a replacement barrel for use with the same ammunition or a barrel configured for shooting a different ammunition caliber or type) includes three main components including a receiver subassembly 212, a barrel subassembly 214 and a forend subassembly 200. The receiver subassembly 212 includes a receiver housing 300 with a central lumen defining a plurality of substantially cylindrical contiguous cavities aligned along a central axis 300CA. The barrel assembly's bore is automatically forced into axial alignment with central axis 300CA when a user tightens a barrel coupler nut 500 against a barrel extension 400 due to the centering force generated when the extension's centering surface 410 bears against the coupler nut's cooperating centering surface 520.

Abstract: A free-floating rifle rail and barrel locking system that provides a barrel assembly and rail assembly, which is detachable from the main body of a rifle without tools. This is advantageous for quick field breakdown and/or rifle modification. The user has the option to disassemble the rifle for easy transport, to change barrel length, to change barrel caliber or change rail configurations. The rails are free-floating, meaning the rails do not come in contact with the barrel and thus do not impact the precision of the rifle.

Abstract: An upper receiver assembly for a firearm having an upper receiver with an integral barrel nut, a handguard assembly and a barrel nut assembly with a barrel and lock nut is provided. The barrel is received by the upper receiver and is secured directly to the upper receiver using the lock nut. The upper receiver also includes an integral handguard mounting member to which the handguard assembly may be directly attached. The upper receiver assembly allows the user to attach both the barrel and handguard assemblies directly to the upper receiver, independently of one another.
