Abstract: A firearm receiver includes a lower receiver body having a pair of takedown pin openings that are positioned along each side, and a bolt channel that extends diagonally from the back end of the receiver body to the inside of the receiver body. A takedown pin assembly is positioned within the receiver body and is in communication with the bolt channel. The takedown pin assembly including a takedown pin that is selectively positioned within the pair of takedown pin openings. The takedown pin assembly including a cam-pin and securement bolt that engage a lock tensioner that is connected to the takedown pin. The cam-pin transitioning between an engaged position and a disengaged position. In the engaged position, the cam-pin imparts a downward force onto the lock tensioner, takedown pin and an upper receiver that is connected to the takedown pin.

Abstract: A muzzle brake device includes a main body having a receiver opening, a discharge opening, a central bore, and a plurality of discharge channels extending outward from the central bore at locations between the receiver opening and the discharge opening. A plurality of raised inlet members are disposed along the central bore and are in communication with the plurality of discharge channels. A separation distance between the channels is complementary to the length of the projectile to which the weapon on which the device is attached, and each of the discharge channels are arranged to emulate the vane of a turbine engine, so as to produce a mechanical force that counteracts the recoil of the weapon to which the device is attached.

Abstract: A concentric rifle barrel assembly includes an outer sleeve having a plurality of threads along the first and second ends, an elongated rifle barrel, and a locking nut. The first end of the rifle barrel is removably positioned within the sleeve and includes a chamber that is sized to receive a firearm cartridge. Threads on the locking nut engage the second end of the sleeve, and a positioning ring that is located a first distance from the first end of the rifle barrel. The first distance being complementary to the length of the sleeve minus the length of the rim of the firearm cartridge for which the barrel is designed to accommodate. Fluting is provided along one or both of the rifle barrel and the sleeve, and the sleeve is designed to receive any number of different rifle barrels each sized to accommodate cartridges of different sizes and calibers.
