Abstract: A modular armorer's stand has a block that, on one end, can engage the magazine well of a firearm frame. The other end of the block has a tongue that can be slid into a base. The base can be mounted to a surface such as a work bench. As such, the frame is held solidly in place for gunsmithing. The firearm's magazine release can engage a notch in the block. Each block can be sized specifically for a certain firearm or firearm family while every block has a tongue that can be held by the base. An armorer therefore needs a single solidly mounted base and that base can hold various blocks that, in turn, hold various firearms.

Abstract: A bayonet mounting fixture can adapt a rifle having a mounting rail to also have a bayonet mount. Previously, bayonets were often mounted to a firearm by passing the barrel through a hole in the guard and then attaching the rear end of the bayonet to a bayonet mount or mounting lug further back. The bayonet mounting fixture can have a forward mount and a rear mount attached to the mounting rail. The forward mount has a round piece that can go inside the hole in the bayonet's guard. The rear mount can have a mounting lug to which the rear end of the bayonet is attached.

Abstract: A handguard is attached to a M16/M4 family firearm by sliding the handguard onto the barrel nut, rotating the handguard relative to the barrel nut and then positioning a timing pin in one of the scallops of the barrel nut sprocket to lock the handguard in position. The back of the hand guard has grooves and ridged matching the barrel nuts teeth and sprockets. Rotating the handguard causes the teeth to enter into slots in the ridges to thereby prevent the handguard from pulling free. A clamping mechanism in the handguard can clamp onto the barrel nut. The addition of friction bushings attached to the inside of the handguard and behind the barrel nut sprocket can provide for even stronger retention.

Abstract: Covers for key lock mounting systems on small arms such as the AR or M4 family of rifles and carbines can provide protection for the firearm and comfort for the operator. The cover has keyhole grips that are pressed into the key lock mounting points in mounting system. The cover is held seated against the surface of the mounting system by the shape and resilience of keyhole grips. V-notch keyhole grips can attach to keyhole shaped mounting points and slot shaped mounting points.

Abstract: A stacked ordnance device provides a disposable and optionally non-reusable projectile weapon. A gun barrel can be formed by holding two half barrels together such that separating the halves exposes the length of the bore. Stacked ordnance devices have multiple projectiles, seals, and charges positioned sequentially in the gun barrel. A controller can electronically trigger igniters that ignite the charges and fire the projectiles. The device can have more than one gun barrel and the gun barrels can be made from plastic. Multi-barrel devices can have gun barrels arranged radially around and damped to a backbone.

Abstract: A firearm can have a handguard having an inner section and an outer section with the outer section having circuitry and control devices for controlling electronic devices. The electronic devices can be part of the outer section. The inner section attaches to the firearm similarly to a current art handguard. The outer section attaches to the inner section. Different functionality can be obtained through the attachment of different outer sections to the inner section. The outer section can obtain electrical power from a power supply attached to or integrated with the firearm. The outer section can alternatively receive electrical power from a power supply carried by a person in a back pack or vest.

Abstract: The present invention is a modular stock system for rifles. The system replaces the rifle's buffer tube with a modified one containing a mount for a constant cheek weld and a rail track for adjustment. A stock module then mounts on the replacement buffer tube. The stock module is interchangeable depending on the user's needs. Various configurations of the stock module are discussed, including adjustable stocks, fixed stocks, and specialized stocks. The stock module may be made even further modular by the addition of rail system.
