Abstract: The present disclosure provides a method of creating a visible indicator upon a firearm magazine. The method may comprise fabricating a plurality of rectangular matrices of divots on an exterior surface of the magazine, the divots having concave surfaces, each matrix comprising a plurality of rows of divots and a plurality of columns of divots. A first divot of a first row is also a first divot of a first column, the first divot forming a substantially straight line with each other divot of the first column, and a first divot of a second row is also a second divot of the first column. The method may then comprise marking, with paint or ink, at least one of the divots.

Abstract: An improved firearm accessory mounting interface is herein disclosed. The interface can include one or more sets of first and second fasteners that interface through an elongated slot in a firearm in order to mount a firearm accessory to a firearm. The second fastener can be shaped and sized to clear the elongated slot and can, upon clearing the elongated slot, be pivoted to an oblique orientation relative to the elongated slot so that the second fastener cannot be retracted. The first fastener can continue to be turned thus drawing the first and second fasteners toward each other and locking the accessory to the firearm.

Abstract: A linking system for rimmed ammunition is disclosed. The linking system features individual links that each encompass one ammunition cartridge while having an arcuate lateral arm which encompasses a neighboring link and associated cartridge. A plurality of collet arms secure the cartridge and separate as the cartridge is forced forward in the delinking process. Angular momenta from the feeding motion and the rotational motion of the de-linking assembly combine to rotate a first link away and apart from the next associated link.

Abstract: The present invention is an ammunition magazine, preferably made of a glass fiber reinforced polymer, utilizing a structurally enhancing ridge, angular guide rails and a follower made to interface with said guide rails to reduce wobble. The preferred embodiment also features a protective cover that distributes forces from the spring to more structurally sound areas of the magazine, thus reducing feed end splay, and an ammunition indication system comprised of at least one window and a noticeable marker on the follower spring. The follower and magazine casing are also designed to interface to prevent the follower from popping out of the feed end and the floor plate of the magazine utilizes a locking plate and sliding relationship between the floor plate, locking plate and magazine to secure the floor plate onto the magazine casing. The cover features built in tools for, among other things, unloading and disassembling the magazine.

Abstract: The present invention is a spring-biased folding firearm that stows compactly and safely. The firearm has three main components: a stock, a receiver and a grip/magazine combination. In folding, the stock folds over the receiver, sandwiching the grip/magazine between the components. When folded, the magazine over-inserts into the grip housing, allowing the stock to clear and providing additional safety when stowed by isolating the ammunition feed. A buttplate latches over the open joint to contain the unit and further secure it. When stowed, the bolt is disengaged from the ammunition feed supply, preventing accidental firing, so a loaded round can be safely carried in the chamber—allowing for immediate use of the firearm upon opening. The weapon is deployed through single-handed actuation and is spring-assisted into firing position. Currently the firearm uses readily available aftermarket parts for easier replacement if necessary and does contain hardware for mounting accessories.

Abstract: The present invention is a sling system utilizing a rear sling fitting for a long firearm, such as a rifle. Such fittings typically are positioned between the stock and receiver. It presents a fitting body with an aperture to slide over a rifle receiver tube and a connection bar extending from a reverse of the fitting body. A point-type sling attachment may then be attached to the connection bar and be able to slide left and right across the back of the weapon, allowing for quickly adaptable left or right positioning of the weapon. Registration geometry may be added and positioned to further allow interface with weapon geometry and prevent rotation of the fitting during use. The connection bar may be positioned on another component of the weapon, such as the receiver or the stock, should the weapon not have a receiver extension tube. A convertible sling and forward sling mount are also disclosed for cooperative use with the fitting, completing the system.

Abstract: The present invention is an improved charging handle for a firearm. The handle is generally non-reciprocating and features a user activated forward assist. The major components are an actuator to provide charging function and upon which other components are mounted, a spring biased lever with a hook which biases downward so that the hook may interface a bolt carrier when the lever is activated, and a blade upon which handle structure is mounted. In the preferred embodiment, the handle is ambidextrous and features a spring detent to keep it in stowed position until the user desires use. The handle will only reciprocate when the lever is activated, which in turn requires intentional user action, thereby providing a relatively safer weapon to operate.
