Adjustable gas block for a firearm

Abstract

A gas block comprising a gas tube channel, a barrel channel, a gas port extending from the gas tube channel towards the barrel channel, a slot extending disposed between the gas port and the barrel channel, and an adjustment mechanism set within the slot and movably coupled to the gas block.

What is claimed is: 
     
         1 . A gas block comprising:
 a receiver end, a muzzle end, a top side, a bottom side, a first side, and a second side;   a gas tube channel extending from the receiver end towards the muzzle end;   a barrel channel extending from the receiver end to the muzzle end;   a gas port extending from the gas tube channel towards the barrel channel;   a slot extending from the first side to the second side and disposed between the gas port and the barrel channel; and   an adjustment mechanism set within the slot and movably coupled to the gas block, the adjustment mechanism comprising a plurality of pinholes, rotatably aligning with the gas port.   
     
     
         2 . The gas block of  claim 1 , wherein the adjustment mechanism is an adjustment wheel. 
     
     
         3 . The gas block of  claim 1 , wherein each of the plurality of pinholes has a different cross-sectional area. 
     
     
         4 . The gas block of  claim 1 , wherein each of the plurality of pinholes has a circular cross-section and wherein the diameter of the circular cross-section for each of the plurality of pinholes is different. 
     
     
         5 . The gas block of  claim 2 , wherein the adjustment wheel comprises a plurality of grooves, wherein at least one of the plurality of grooves is configured to engage a locking fastener configured to secure the adjustment wheel. 
     
     
         6 . The gas block of  claim 5 , further comprising an adjustment fastener and a plate, wherein the adjustment fastener is configured to move in and out of an adjustment channel. 
     
     
         7 . A gas block comprising:
 a gas tube channel;   a barrel channel;   a gas port extending from the gas tube channel towards the barrel channel;   a slot extending disposed between the gas port and the barrel channel; and   an adjustment mechanism set within the slot and movably coupled to the gas block.   
     
     
         8 . The gas block of  claim 7 , wherein the adjustment mechanism is an adjustment wheel. 
     
     
         9 . The gas block of  claim 8 , wherein the adjustment wheel comprises a plurality of pinholes 
     
     
         10 . The gas block of  claim 9 , wherein the plurality of pinholes rotatably align with the gas port. 
     
     
         11 . The gas block of  claim 9 , wherein each of the plurality of pinholes has a different cross-sectional area. 
     
     
         12 . The gas block of  claim 9 , wherein each of the plurality of pinholes has a circular cross-section, and wherein the diameter of the circular cross-section for each of the plurality of pinholes is different. 
     
     
         13 . The gas block of  claim 8 , wherein the adjustment wheel comprises a plurality of grooves, wherein at least one of the plurality of grooves is configured to engage a locking fastener configured to secure the adjustment wheel. 
     
     
         14 . The gas block of  claim 13 , further comprising an adjustment fastener and a plate, wherein the adjustment fastener is configured to move in and out of an adjustment channel. 
     
     
         15 . A method for adjusting a flow of gas about a gas block, the method comprising:
 providing a gas tube channel;   providing a barrel channel;   providing a gas port extending from the gas tube channel towards the barrel channel;   providing a slot extending disposed between the gas port and the barrel channel; and   providing an adjustment mechanism set within the slot and movably coupled to the gas block, wherein the adjustment mechanism is configurable to adjust the flow of gas about the gas block.   
     
     
         16 . The method of  claim 15 , wherein the adjustment mechanism is an adjustment wheel. 
     
     
         17 . The method of  claim 16 , wherein the adjustment wheel comprises a plurality of pinholes 
     
     
         18 . The method of  claim 17 , wherein the plurality of pinholes rotatably align with the gas port. 
     
     
         19 . The method of  claim 17 , wherein each of the plurality of pinholes has a different cross-sectional area. 
     
     
         20 . The method of  claim 17 , wherein each of the plurality of pinholes has a circular cross-section, and wherein the diameter of the circular cross-section for each of the plurality of pinholes is different.
