Abstract

A system for an adjustable gas block. The gas block body has a main chamber fluidly coupled to a gas aperture which is fluidly connected to a plunger channel and a gas return path. Downstream of the gas block body is a plunger assembly which includes a ring and a plunger. Further downstream is an adjustment knob which is coupled to the gas block body and which is adjustable upstream and downstream relative to the gas block body. The volume of plunger inserted into the channel path is controlled by the adjustment knob.

Claims

1. A system for an adjustable gas block, said system comprising:

a gas block body comprising a main chamber fluidly coupled to a gas aperture, wherein said gas aperture is fluidly connected with a gas return path and a plunger channel;

a plunger assembly downstream from said gas block body, wherein said plunger assembly comprises a ring and a plunger;

an adjustment knob located downstream from said plunger assembly;

wherein said adjustment knob couples to said gas block body, and wherein when said adjustment knob is manipulated, said plunger is urged upstream and downstream relative to said gas block body.

2. The system of claim 1 wherein said plunger extends upstream from said ring.

3. The system of claim 1 wherein said plunger is releasably coupled to said ring.

4. The system of claim 1 wherein said gas block body comprises an elongated coupling member and a coupling device, and wherein said adjustment knob couples with said coupling device.

5. The system of claim 4 wherein said plunger assembly rests on said elongated coupling member.

6. The system of claim 1 further comprising a wavy spring downstream from said gas block body and upstream from said plunger assembly.

7. The system of claim 1 wherein said plunger assembly comprises at least one projection, and wherein said adjustment knob comprises at least two detents, and wherein said detents receive said at least one projection.

8. The system of claim 1 wherein at least a portion of plunger extends in the plunger channel.

9. The system of claim 8 wherein said plunger comprises a smooth surface.

10. The system of claim 8 wherein the amount of plunger received in said gas return path is adjusted with said adjustment knob.

11. The system of claim 1 wherein gas block body, said ring, and said adjustment knob each comprise a central and aligned void.

12. The system of claim 1 wherein said gas return path, said plunger channel, and said main chamber are approximately parallel, and wherein said gas return path is located atop said plunger channel, and wherein said plunger channel is located atop said main chamber.

13. The system of claim 1 further comprising a firearm with a barrel, wherein said barrel is inserted through said central chamber and extends through the ring of the plunger assembly and through the adjustment knob.

14. The system of claim 13 wherein gas block surrounds the outer periphery of said barrel.

15. The system of claim 13 wherein said firearm comprises a firearm gas tube, and wherein said gas return path is fluidly coupled to said firearm gas tube.

16. The system of claim 1 wherein no tools are necessary to move said plunger upstream or downstream relative to the gas body block.

17. The system of claim 1 wherein said adjustment knob has no direct contact with exhaust gasses.

18. The system of claim 1 wherein said adjustment knob advances upstream and downstream.

19. The system of claim 1 wherein said adjustment knob does not advance upstream or downstream.
