Abstract: A reconfigurable modular interface system for an integrated and standardized weapons system is disclosed. An upper accessory mount is provided that includes one interface for mounting to the desired primary mounting component, such as a firearm. The upper accessory mount further includes a second interface along its bottom edge for attaching accessories thereto. Accessories to be mounted into the modular interface system may either include mating formations that are provided as integrated OEM parts or through the use of retrofit adapter panels mounted to the secondary device.

Abstract: An improved mounting assembly is provided that is configured to be releasably mounted onto a standard dovetail rail profile and includes a positive index that corresponds to a fully opened position. The mounting assembly includes a boss formation that extends from one side thereof. A camming member and an actuator arm are installed into the boss formation and serve as a means for engaging and disengaging the mounting assembly relative to the dovetail rail. A shoulder formation is provided on the boss formation adjacent the actuator arm and extends upwardly such that the shoulder prevents over rotation of the actuator arm allowing the actuator arm to be positioned in a fully disengaged, open position where it will not interfere with removal or installation of the mounting assembly relative to the rail.

Abstract: A low profile, self-aligning, flip-up mechanism for aiming devices used with firearms. The mechanism folds the aiming device into the contour of the firearm during non-use. The mechanism is spring-loaded and flips into a vertical operational position with a simple movement of a finger or thumb. The mechanism includes at least two separate aiming elements that are mounted in a fashion that allows them to rotate relative to one another thereby facilitating a smaller storage profile. The mechanism also causes the aiming device to self-align itself as it moves into an operational position assuring vertical position repeatability.

Abstract: A positively aligning, quick mount assembly for interfacing an auxiliary sighting device such as an optical scope with a firearm is disclosed. The positive-aligning quick mount device includes a sight receiver that is attached to a firearm utilizing a firearm interface and includes a mounting ring that supports the sighting device and is configured to be received and retained by the sight receiver. It is further designed to allow quick and easy mounting, removal and re-mounting of auxiliary sights on any firearm while eliminating the need to re-adjust or zero the scope when it is replaced in its mounted position on the firearm.

Abstract: A laser module adapted to being joined to a modular sleeve upper handguard piece top longitudinal gap. The laser module has two, parallel elongated submodules positioned so that an elongated, generally rectangular space is formed between the submodules. The laser module elongated space fits onto the longitudinal gap and the submodules fit along the upper handguard sides in the shallow upper channels. An upper handguard interface element is attached centrally over the laser module top. Each submodule has means for azimuth and height adjustments.

Abstract: A Swan universal receiver sleeve attached to the top of a firearm upper receiver and extended forward above the firearm barrel to a position just short of the firearm front sight. The underside of the rear portion of the sleeve is fixedly attached to the receiver top. The underside of the forward portion of the sleeve has an upper handguard piece attached thereto. A bottom handguard piece is fitted about the bottom of the gun barrel and is attached to the upper handguard piece. The handguard pieces are not physically connected in any way to the gun barrel. The sleeve is self supported by the connection of the rear portion underside to the receiver top. A special yoke is inserted about the barrel nut of the firearm to which the modular sleeve is attached. The special yoke reinforces the modular sleeve while keeping the firearm barrel free floating.
