Abstract

A barrel nut assembly for use on a variety of firearms is provided. The assembly is made up of a barrel nut, generally cylindrical in shape with a threaded central bore, and an externally threaded locknut which is used in conjunction with the barrel nut to secure a barrel to a firearm upper receiver. The barrel nut has an integral bushing on its exterior constructed to support either the gas tube or piston of the host firearm's operating system. The barrel nut is configured so that it may be independently and non-rotationally held within a vice or other fixture during installation of the barrel and while the locknut is tightened to a preset torque to hold the barrel in place. The barrel nut assembly affords the user a method and apparatus that aligns a central bore in the bushing with the opening in the upper receiver that receives an operating system component of the firearm while the barrel nut is independent of the torque applied to the locknut to properly secure the barrel to the upper receiver.

Abstract

An adjustable gas block for a gas operated firearm is provided that offers the user a means by which the volume of gas being directed to the host rifle's operating system can be adjusted. The adjustable gas block provides two positions of adjustment, with the position of use being selected based on whether or not a back pressure increasing device, such as a noise suppressor or a silencer, is mounted on the firearm. A first position provides the optimal volume of gas into the gas operating system for it to operate properly based on its factory configuration and in the absence of a back pressure increasing device. A second position is available for use when the back pressure is increased due to the presence of a back pressure increasing device. The second position exposes a port through which a portion of the volume of gas from the barrel is vented into a secondary chamber prior to being released into the atmosphere. By venting a portion of the gas into a secondary chamber, the amount of gas received by the operating system is reduced to a volume that is substantially equal to the volume of gas that would be received by the operating system in the absence of a back pressure increasing device. No tools are required to select either of the positions provided by the gas block.

Abstract

A firearm including a barrel, receiver, indirect gas system and an adjustable gas block. Four positions of adjustment are provided for on the adjustable gas block, each of which provides a different setting to regulate gas flow into the host firearm's operating system. A position of adjustment is selected based on how the firearm is being used. The provided positions of adjustment are calibrated for the standard use of the host firearm, use of a silencer, use of the firearm under hard or adverse conditions or when it is necessary to increase the firearm's rate of fire, and to block the flow of gas into the operating system. The provided gas block is designed to function with an indirect gas operating system, but could be adapted for use with a direct gas impingement system as well. Excess gas from the operating system is not vented from the gas block thereby eliminating the generation of additional muzzle flash and sound. No tool is required to manipulate the adjustment mechanism of the gas block.

Abstract

A firing pin safety catch mechanism for a firearm, especially an auto-loading firearm which operates with a closed action such as found on the United States Military's M16 and its various derivatives. The firearm includes a firing pin which is housed within a bolt carrier group and which is capable of being moved from a rest position in which its proximal end is out of the travel path of the hammer to a firing position. The safety catch mechanism includes a safety catch, a pin and a spring for biasing the safety catch to hold the firing pin in its rest position to prevent the unintentional movement of the firing pin and thereby prevent the unintentional discharge of the host firearm. The safety catch includes a cam surface cooperating with the hammer so that the catch is released from engagement with the firing pin when the hammer has substantially completed its path of travel.

Abstract

A firearm has a frame with a barrel connected to the frame and defining a barrel axis. The barrel has a rear end defining a chamber, and a bolt assembly reciprocates with respect to the chamber between a closed position adjacent the chamber, and an open position away from the chamber. A fire control assembly includes a trigger and a selector switch with a semi-automatic position and a fully-automatic position. The fire control assembly includes a bolt assembly sear operably engaging the bolt. The fire control assembly operates when the selector switch is in the semi-automatic position in response to pulling the trigger to discharge the firearm, to load a cartridge, and to position the bolt in the closed position. The fire control assembly operates when the selector switch is in the fully-automatic position in response to pulling the trigger to discharge the firearm, and to hold the bolt in the open position. The fire control may include a sub-frame connected to the frame and to the bolt assembly sear, and may include a safety sear that prevents firing out of battery when in either full-auto or semi-auto modes. The fire control system may include a facility that momentarily maintains the trigger in a firing position when it is released while the bolt is moving forward from the open position.
