A conducting hinge device is adapted to be mounted to an electric toy gun that includes a first body-section, a second body-section pivotally connected to the first body-section, an electric motor unit, and a battery unit. The conducting hinge device includes a conducting unit and a hinge conductor unit. The conducting unit is installed between the first body-section and the second body-section, and includes two pin members for being electrically connected to the electric motor unit. The hinge conductor unit includes two hinge leaves that are mounted co-movably to the second body-section, and that are each sleeved on a respective one of the pin members and electrically connected to the battery.

Storage plugs configured to receive batteries, tools, and/or accessories are provided. The storage plug includes an insert, insertable within a recess of a firearm grip, and one or more channels, each extending from a top surface of the insert. A wall disposed between indents extending from a bottom surface of the insert is configured to be held by a user during insertion or removal of the insert. One or more ridges disposed around the insert frictionally engage with an inner surface defining the recess of the firearm grip. Each channel is configured to receive one or more batteries, tools, and/or accessories. Each battery is one of a cylindrical battery, a square or rectangular battery, or a coin- or button-cell battery. Each tool is a multi-tool, a hex key, or another tool or accessory associated with a firearm or otherwise desirable to be carried in the storage plug.

An accessory control handgrip apparatus for weapon includes a rail clamp assembly, a grip base extending from the grip base assembly, a grip sleeve slidably received on the grip base, a keypad disposed on the grip sleeve, and one or more connectors for operably coupling the keypad to an accessory device.

An adjustable stock system for a firearm can include a buttstock slider configured to be slidably attached to the firearm for moving relative to the firearm between a collapsed position and at least one extended position. The buttstock slider can include a plurality of buttstock grooves defined therein. The system can include a lower stock assembly that is configured to mount to a firearm and a latch assembly disposed within the lower stock assembly. The latch assembly is configured to be moveable between a latched position where the buttstock slider cannot slide relative to the firearm and an unlatched position where the buttstock slider is free to slide relative to the firearm. The latch assembly can include at least one latch tooth configured to mate with the plurality of buttstock slider grooves when the latch assembly is in the latched position. The latch assembly is biased to the latched position. The system includes an actuator assembly configured to move the latch assembly between the latched position and the unlatched position.

A buttstock assembly configured to work in conjunction with a compact buffer assembly consisting of a buffer tube, spring and bolt carrier with an integral buffer is provided. The buttstock assembly, buffer tube and bolt carrier are configured to work with AR15/M16 type firearms and their derivatives. By incorporating the buffer onto the bolt carrier, which is used in conjunction with a buffer tube of reduced length, the overall length of the host firearm is reduced by approximately 3.2 inches. No permanent modification need be made to the host firearm in order to utilize the compact buffer assembly and buttstock assembly disclosed herein.
