The invention is a bolt carrier with a modified cam path that prevents undesired contact between a cam pin and the sidewall of an upper receiver.

Bolt carrier with a modified cam path

In one embodiment the invention is a hand guard, comprising: a generally hollow cylindrical body having a rail securing top surface; a top Picatinny rail securable to the rail securing top surface. The top rail is in slidable engagement with the rail securing top surface such that the top Picatinny rail is removable from the top surface. The generally hollow cylindrical body is populated with vent holes. In another embodiment an upper receiver is provided, the upper receiver includes a front face located at a front end of the upper receiver, the upper receiver having a Picatinny rail atop thereof, the Picatinny rail having a last rail located at a front end of the Picatinny rail, the last rail is aligned with the front face. In another embodiment the hand guard has a fixed Picatinny rail atop thereof. At least one plug is optionally provided for fitting into vent holes.

Handguards and upper receivers alone and in combination

In one aspect of the invention a buffer retaining pin is provided that comprises an elongate body. The elongate body comprises a cylindrical body portion. The elongate body has a longitudinal axis, a proximal end, and an opposite open distal end. The cylindrical body has an inner chamber in communication with the open distal end. A tooth is located at the proximal end of the elongate body. The tooth is integral with and extends from the cylindrical body such that the cylindrical body portion extends between the tooth and the open distal end. The tooth defines a top side, a left side, a right side, a front face, and a rear face. The front face of the tooth extends in a plane such that the plane of the front face intersects the longitudinal axis.

Buffer retaining pin

A gas operating system for a firearm includes a gas block, a barrel nut that maintains the gas block at a predetermined axial position on a barrel of the firearm, a member that is movable with respect to the gas block axially with respect to the barrel in response to pressure exerted by expanding propellant gases conveyed thereto by the gas block and a mechanical linkage receiving a force form the member urging it in an axial direction of the barrel and coupled with a loading and ejection mechanism of the firearm to convey the force thereto for operating the loading and ejection mechanism. Various embodiments of gas block assemblies and operating rods for gas operating systems for firearms are provided.

Gas operating systems, subsystems, components and processes

Processes and systems are disclosed for recording data relating to a shot by a projectile weapon. Environment data occurring prior to data indicating the occurrence of a shot by the projectile weapon is retained for subsequent evaluation. Such environment data includes, but is not limited to, ambient audio data, video data produced by a video camera associated with the projectile weapon, GPS data representing locations of the projectile weapon, electronic compass data representing orientations of the projectile weapon and acceleration data representing accelerations of the projectile weapon.

Processes and systems for monitoring environments of projectile weapons

Processes and systems for detecting a shot by a projectile weapon are disclosed. Data is obtained along at least two different axes for use in determining whether a shot has taken place based on an evaluation by a processor. In certain embodiments, multiple detection systems are positioned on a weapons platform mounting multiple projectile weapons, and each is configured to detect only a shot by a respective one of the projectile weapons.

Processes and systems for monitoring usage of projectile weapons

A self-cleaning gas operating system for a firearm having a conventional bolt carrier assembly is disclosed comprising: a nozzle assembly having a nozzle in direct communication with a port on the muzzle; said nozzle assembly nested within a piston cup having a vent, a connecting rod operationally linking the piston cup to a spring loaded operating rod which is substantially co-axial to a bolt carrier key having a striking portion, said striking portion having a concave strike face in contact with said operating rod, wherein gas discharged from a fired cartridge displaces the piston cup and causes the operating rod to strike the strike face displacing the bolt assembly.

Self-cleaning gas operating system for a firearm

A modular receiver system for firearms comprising a barrel and receiver assembly providing a quick changeover coupling means for connecting the barrel to the receiver, wherein the coupling means comprises a barrel retaining bushing and a pair of opposed cam surfaces on the receiver for hinged engagement of the cam surfaces against the barrel, and wherein the modular receiver system further comprises a rail system for mounting ancillary firearms equipments.

Modular receiver system

The present invention provides a method and apparatus for generating electrical energy. In particular, the invention provides devices and methods by which the explosive energy provided by highly combustible propulsive sources, such as solid, liquid and gaseous propellants, can be used to generate sufficient electrical energy to power devices such as high energy spark generators, portable cardiac defibrilators, lasers and the like. The apparatus used can be compact, highly portable, and reusable. By providing a storage device and electrical discharge control, the method and apparatus can be adapted to power low energy devices over an extended period of time.
