Benefits of technology

The patent describes an improved adjustable gas block for gas-operated auto-loading firearms. The gas block has a main housing with a longitudinal bore for the firearm's barrel and gas tube, and a gas transfer port connected to both bores. The gas block has a click adjustment valve screw that can be adjusted to compensate for field variables such as ammunition loading, bullet weight, atmospheric temperature, and cartridge caliber. The gas block can be adjusted using a separate tool or a finger-manipulable knob. The gas block allows for precise and repeatable adjustments, and can be easily installed and removed from firearms. The technical effects of the improved gas block include improved accuracy, versatility, and adaptability to a wide variety of firearms and field variables.

Problems solved by technology

Both are undesirable characteristics when a firearm is sound-suppressed.

Embodiment Construction

[0080]An auto-loading firearm's gas-operating system is one which utilizes a portion of the firearm cartridge's propellant gas as the energy source to operate the firearm's auto-loading mechanism. The illustrated embodiments of the invention are designed to provide users of gas-operated auto-loading firearms with a means of precisely and repeatably adjusting the amount of gas which is allowed to pass from the barrel of a host firearm into its gas-operating system, thus providing the ability to optimize the operation of a firearm by compensating for variations in ammunition loading, bullet weight, atmospheric temperature, cartridge caliber, and for the installation / removal of a silencer. The term “gas-operated auto-loading firearm” as used in this document includes, but is not limited to, direct impingement systems such as M16 / AR15 / AR10 / M4 type of firearms, as well as firearms that utilize a piston and cylinder in their gas-operating system. Please note that while the illustrated emb...

Abstract

An adjustable gas block designed to interface with the gas-operating system of an auto-loading firearm. This design provides continuously adjustable gas flow, from fully closed to fully open, in small, discrete, uniform, and fully-repeatable increments.The design works by means of a click adjustment valve screw which has a number of grooves that are engaged by a spring-loaded detent. As the screw is turned in or out, either by a tool or by an integrated finger-adjustable knob or handle, the clicks of the detent provide both audible and tactile feedback to the user. This allows a user to optimize the operation of a firearm by responding to variations in ammunition loading, bullet weight, atmospheric temperature, cartridge caliber, and for the installation / removal of a silencer, each of which changes the volume and pressure characteristics of the gas-operating system.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of provisional patent application No. 61 / 550,569, filed 2011 Oct. 24 by the present inventor.FEDERALLY SPONSORED RESEARCH[0002]Not Applicable.SEQUENCE LISTING[0003]Not Applicable.BACKGROUND-FIELD OF INVENTION[0004]This invention relates to gas-operated auto-loading firearms, and specifically to user-adjustable gas blocks for such firearms.BACKGROUND-PRIOR ART[0005]A gas block for an auto-loading firearm is a device that is placed usually on the barrel of an auto-loading firearm, and used as a means to tap, collect, restrict, and direct the flow of propellant gas from the firearm's barrel into the auto-loading mechanism so as to provide the necessary energy to operate the auto-loading firearm. Adjustable gas blocks have been used on military auto-loading firearms for decades, as seen in such firearms as: the Soviet SVD; Yugoslavia's models 70, 76, and 95; the Belgian FAL; and recent Belgian SCAR rifles. ...
