Abstract: Embodiments herein relate to the field of weapon accessories, and, more specifically, to modular, electrically powered weapon accessories. Various embodiments include powered modular vertical foregrips that may serve as platforms for multiple firearms accessories, such as modular laser and/or LED lighting and/or sighting systems, radiofrequency receiver and/or transmitter systems, and/or other powered accessories. Various embodiments may be adapted to couple to a mounting rail, such as a Picatinny or Weaver rail, and particular embodiments may be adapted to couple to a lower hand guard quad-rail of an M4 or other small arms weapon. Systems in accordance with various embodiments may provide a platform that may consolidate multiple accessory devices and functions into a single ergonomic and compact unit.

Abstract: Embodiments provide modular illumination systems that may be used with any handgun platform, and are not specific to any make or model. Some embodiments may provide lighting, for instance visible light and/or infrared light for use in low light or dark environments. Also provided in various embodiments are aiming and/or sighting systems that may be equipped with an IR sight or a laser sight, such as a red or green laser. In various embodiments, the illumination modules may couple to the handgun via a mounting member that is integral to the handgun body, and the mounting member may be recessed or otherwise concealed and/or protected by the handgun body. Thus, in various embodiments, no portion of the mounting member (or the corresponding mounting element on the illumination module) is exposed or visible when the illumination module is coupled to the mounting member, and a conventional holster may be used.
