Abstract: An gas supply system for use with an airsoft gun to power a pneumatic engine contained within a receiver of the airsoft gun. The gas supply system includes a bottle of pressurized gas that supplies pressurized gas at a first pressure to the receiver. A pressure regulator is located between the supply of pressurized gas and the pneumatic drive engine and operates to reduce the pressure of the gas from the first pressure to a second pressure. The pressure regulator is supported on the airsoft gun and allows the pressure of gas supplied to the pneumatic engine of the airsoft gun to be regulated. The pressure regulator includes an adjustment dial that allows an operator to change the pressure of gas supplied to the airsoft gun. The pressure regulator can be located between the bottle of pressurized gas and the receiver.

Abstract: Implementations of a rear sight block for AK-type rifles are provided. In some implementations, the rear sight block may be drop-in-compatible with most AK-type rifles and performs several functions (e.g., providing a guide hole for the piston of an AK-type rifles operating system) associated with prior art rear sight blocks found on AK-type rifles. In some implementations, the rear sight block disclosed herein comprises an optic mounting interface having an integral rear sight notch therein, and at least one accessory mounting interface. In some implementations, the optic mounting interface places an optical gun sight secured thereto in line with the iron sights of the host AK-type rifle. In some implementations, the accessory mounting interface may be used to position a flashlight, laser, and/or other firearm accessory on the left (or right) side of the rear sight block.

Abstract: A method of forming a gun barrel is disclosed that includes applying one or more coatings to the gun barrel such as just a top coating, or a bond coating and then a top coating. The method may also include (before applying one or more coatings): threading an outer surface of the gun barrel proximate a first end of the gun barrel; threadedly coupling the first end of the gun barrel to a gun chamber; fixedly coupling the gun barrel to the gun chamber.

Abstract: A munition that is adapted to enhance fragmentation effects upon detonation includes preformed fragments between a casing and a shell. The overall mass of the preformed fragments is greater than the overall combined mass of the casing and the shell for enhancing the degree of controlled fragmentation compared to uncontrolled fragmentation. By enhancing the dispersal of controlled fragmentation, the overall fragmentation area coverage and fragmentation pattern density may also be enhanced while limiting travel of the fragmentation beyond the target area for reducing collateral damage. The preformed fragments may fill a continuous volume between the casing and the shell to effectively utilize the munition volume and to maximize the amount of preformed fragments contained within the shell. The preformed fragments may be free flowing pellets that are poured into the volume between the casing and the shell for enhancing distribution of the fragments and for improving assembly of the munition.
