摘要： In embodiments, a modular rifle includes a lower receiver assembly, an upper receiver assembly, and a coupling mechanism. The upper receiver contains a bolt carrier and a housing enclosing the recoil spring and rod. Within the housing is a counter bore shoulder against which the recoil spring rests. Integrated into the top face of the bolt carrier are compartments, upon which the housing is mounted. Holes in the front of the housing and the upper receiver assembly accommodate the rod. Containing the recoil spring and rod within in the housing mounted to the bolt carrier allows the modular rifle to have a folding, collapsible, or otherwise non-fixed stock. Attached to the rod is a retaining tab, the depression of which allows for the release of the upper receiver from the lower receiver for disassembly of the rifle.

摘要： In embodiments, a modular rifle includes a lower receiver assembly, an upper receiver assembly housing a barrel, and a coupling mechanism. Upper receiver assembly has two portions, an aft portion and fore portion, commonly comprising a hand guard. The barrel is releasably attached to the upper receiver first portion by a hand-tightenable barrel nut sleeve connector. Upper receiver second portion is both releasably attached to the barrel nut connector sleeve and to the upper receiver first portion to prevent the barrel nut connector sleeve from rotating during firing of the rifle and to keep the second portion from detaching during firing of the rifle. Attachment of upper receiver second portion to the barrel nut connector sleeve is accomplished by a removable take-down pin and common screw clamp, which secure the barrel nut connector sleeve. Upper receiver first and second portions are connected by an attachment tab and receptacle.

摘要： A modular rifle includes an upper receiver assembly and a barrel assembly. The upper receiver, typically fashioned from aluminum, can be strengthened by insertion of a hardened metal liner insert inside the aft portion of the upper receiver. The upper receiver liner insert is secured within the aft portion of the upper receiver assembly by engaging screw threads on the liner insert with receiving threads inside the aft portion of the upper receiver and insertion of anchor pins into the aft portion of the upper receiver. The anchor pins impinge the liner insert such that it is prevented from rotating within the upper receiver. The barrel assembly is attached to the liner insert by engaging screw threads on the liner insert with threads within a barrel nut connector sleeve.
