US12292251 - Adjustable gas block for firearm

An adjustable gas block for a firearm comprises a housing adapted to be attached to a barrel of the firearm. The housing has a first passageway adapted to be aligned with a gas port in a barrel of the firearm and a second passageway adapted to receive a gas tube of the firearm, such that a bore of the barrel, the gas port of the barrel, the first passageway, and the gas tube are in fluid communication. A valve member is mounted in the housing for forward and rearward sliding movement and has a first portion and a second portion. The first portion has an upwardly facing surface having a radius of curvature that closely approximates a radius of curvature of an outer diameter of the gas tube, and the second portion has threads. A nut is carried by the housing for rotational movement and has threads mating with the threads on the second portion of the valve. Rotating the nut in a first direction translates the valve member forwardly and rotating the nut in a second opposite direction translates the valve member rearwardly. The axial position of the first portion of the valve member controls the amount of gas passing from the first passageway to the gas tube by completely opening, partially opening, or completely closing the first passageway.

The patent describes an adjustable gas block for firearms that allows for the control of gas flow from a barrel’s gas port to the gas tube through a sliding valve mechanism. By rotating a nut attached to the housing, the user can adjust the position of the valve member to completely open, partially open, or close the gas passageway.

Claim 1

An adjustable gas block for a firearm, comprising: a housing adapted to be attached to a barrel of the firearm, the housing having a first passageway adapted to be aligned with a gas port in a barrel of the firearm and a second passageway adapted to receive a gas tube of the firearm, such that a bore of the barrel, the gas port of the barrel, the first passageway, and the gas tube are in fluid communication, a valve member mounted in the housing for forward and rearward sliding movement and having a first portion and a second portion, the first portion having an upwardly facing surface having a radius of curvature that closely approximates a radius of curvature of an outer diameter of the gas tube, the second portion having threads, and a nut mounted to the housing for rotational movement and having threads mating with the threads on the second portion of the valve member, whereby rotating the nut in a first direction translates the valve member forwardly and rotating the nut in a second opposite direction translates the valve member rearwardly, the axial position of the first portion of the valve member controlling the amount of gas passing from the first passageway to the gas tube by completely opening, partially opening, or completely closing the first passageway. a housing adapted to be attached to a barrel of the firearm, the housing having a first passageway adapted to be aligned with a gas port in a barrel of the firearm and a second passageway adapted to receive a gas tube of the firearm, such that a bore of the barrel, the gas port of the barrel, the first passageway, and the gas tube are in fluid communication, a valve member mounted in the housing for forward and rearward sliding movement and having a first portion and a second portion, the first portion having an upwardly facing surface having a radius of curvature that closely approximates a radius of curvature of an outer diameter of the gas tube, the second portion having threads, and a nut mounted to the housing for rotational movement and having threads mating with the threads on the second portion of the valve member, whereby rotating the nut in a first direction translates the valve member forwardly and rotating the nut in a second opposite direction translates the valve member rearwardly, the axial position of the first portion of the valve member controlling the amount of gas passing from the first passageway to the gas tube by completely opening, partially opening, or completely closing the first passageway.
