Abstract
A gas block for a firearm that includes a body portion having a longitudinal axis; a barrel borehole, adapted to receive at least a portion of a barrel therethrough, extending through the body portion, along the longitudinal axis of the body portion; a gas tube extension portion having a longitudinal axis, wherein at least a portion of the gas tube extension portion extends beyond at least a portion of the body portion; a gas tube borehole extending through the gas tube extension portion, along the longitudinal axis of the gas tube extension portion, wherein the gas tube borehole is adapted to receive at least a portion of a gas tube therein; and a gas port disposed between the barrel borehole and the gas tube borehole, such that the barrel borehole is in fluid communication with the gas tube borehole.
Claims18
A gas block for a firearm, comprising:
- a body portion extending along a longitudinal axis;
- a barrel borehole extending through said body portion, substantially parallel to said longitudinal axis of said body portion, wherein said barrel borehole is adapted to receive at least a portion of a barrel therethrough;
- a gas tube extension portion having a longitudinal axis, wherein at least a portion of said gas tube extension portion extends beyond at least a portion of said body portion;
- a gas tube borehole extending through at least a portion of said gas tube extension portion, along said longitudinal axis of said gas tube extension portion, wherein said gas tube borehole is substantially parallel to said barrel borehole, and wherein said gas tube borehole is adapted to receive at least a portion of a gas tube therein;
- a gas port disposed between said barrel borehole and said gas tube borehole, such that at least a portion of said barrel borehole is in fluid communication with at least a portion of said gas tube borehole;
- a body extension portion having a longitudinal axis, wherein said body extension portion extends beyond at least a portion of said body portion;
- and
- a substantially C-cut portion extending between at least a portion of said gas tube extension portion and at least a portion of said body extension portion, wherein said substantially C-cut portion has foci on a longitudinal axis, and wherein at least a portion of said gas tube extension portion or at least a portion of said body extension portion is adapted to contact at least an exterior portion of said barrel, if said portion of said barrel is positioned through said barrel borehole, said foci lies within said barrel.

A gas block for a firearm, comprising:
- a body portion extending along longitudinal axis, wherein a first end of said body portion includes a substantially planar surface portion and a substantially concave surface portion, and wherein a surface of said substantially concave surface portion is perpendicular to said longitudinal axis of said body portion;
- a barrel borehole extending through said body portion, substantially along said longitudinal axis of said body portion, wherein said barrel borehole is adapted to receive at least a portion of a barrel therethrough;
- a gas tube extension portion having a longitudinal axis, wherein at least a portion of said gas tube extension portion extends beyond at least a portion of said body portion;
- a gas tube borehole extending through at least a portion of said gas tube extension portion, substantially along said longitudinal axis of said gas tube extension portion, wherein said gas tube borehole is substantially parallel to said barrel borehole, and wherein said gas tube borehole is adapted to receive at least a portion of a gas tube therein;
- a gas port disposed between said barrel borehole and said gas tube borehole, such that at least a portion of said barrel borehole is in fluid communication with at least a portion of said gas tube borehole;
- a body extension portion, wherein at least a portion of said body extension portion extends beyond at least a portion of said body portion;
- and a substantially C-cut portion formed between at least a portion of said gas tube extension portion and at least a portion of said body extension portion, wherein said substantially C-cut portion has foci on a longitudinal axis, and wherein at least a portion of said gas tube extension portion or at least a portion of said body extension portion is adapted to contact at least an exterior portion of said barrel, if said portion of said barrel is positioned through said barrel borehole, said foci lies within said barrel.
4 more elements
A gas block for a firearm, comprising:
- a body portion extending along longitudinal axis, wherein a first end of said body portion includes a planar surface portion and a concave surface portion;
- at least one set screw aperture formed through said body portion, wherein said at least one screw aperture is formed perpendicular to said barrel borehole;
- a barrel borehole extending through said body portion, along said longitudinal axis of said body portion, wherein said barrel borehole is adapted to receive at least a portion of a barrel therethrough;
- a gas tube extension portion having a longitudinal axis, wherein at least a portion of said gas tube extension portion extends beyond at least a portion of a second end of said body portion;
- a gas tube borehole extending through at least a portion of said gas tube extension portion, along said longitudinal axis of said gas tube extension portion, wherein said gas tube borehole is parallel to said barrel borehole, and wherein said gas tube borehole is adapted to receive at least a portion of a gas tube therein;
- a gas port disposed between said barrel borehole and said gas tube borehole, such that at least a portion of said barrel borehole is in fluid communication with at least a portion of said gas tube borehole;
- a body extension portion extending beyond at least a portion of said second end of said body portion and extending beyond at least a portion of said gas tube extension portion;
- and a substantially C-cut portion formed between at least a portion of said gas tube extension portion and at least a portion of said body extension portion, wherein said substantially C-cut portion has foci on a longitudinal axis, and wherein at least a portion of said gas tube extension portion or at least a portion of said body extension portion is adapted to contact at least an exterior portion of said barrel, if said portion of said barrel is positioned through said barrel borehole, said foci lies within said barrel.
