Gas block for a firearm

Abstract

This invention relates to a gas block for high rate of fire tactical rifles and carbines such as the M16/AR15 family of firearms. More particularly, an adjustable gas block is disclosed that enables the user to dynamically adjust exhaust gas discharges by manipulating a gas block regulator.

1 . A gas block, comprising:
 a regulator disposed through a regulator slot;   a locking mechanism comprising a pin and a spring, wherein the pin is configured to lock the regulator into one or more select positions, wherein the gas block is configured such that an operator may push the regulator into any one of the one or more select positions using his finger.   
     
     
         2 . The gas block of  claim 1 , further comprising a push surface disposed about a first end of the regulator, wherein the regulator is configured to be pushed into the one or more select positions by pushing the push surface. 
     
     
         3 . The gas block of  claim 1 , wherein the gas block is configured to be secured to a barrel of a firearm. 
     
     
         4 . The gas block of  claim 1 , wherein each select position is configured to allow a predetermined amount of gas through a gas channel disposed through the gas block. 
     
     
         5 . The gas block of  claim 4 , wherein the gas channel further comprises:
 a gas hole disposed on an inner surface of the gas block, wherein the gas hole is configured to receive exhaust gas from a barrel of a fire arm;   a regulator hole disposed through the regulator, wherein the regulator hole is in fluid connection with the gas hole;   a gas directing chamber, wherein the gas directing chamber is in fluid connection with the regulator hole;   a gas tube port, wherein the gas tube port is in fluid connection with the gas directing chamber and wherein the gas tube port it configured to allow gas to flow out of the gas block.   
     
     
         6 . A gas block, comprising:
 a gas channel;   a pin locking mechanism disposed in a pin locking mechanism chamber, wherein the pin locking mechanism comprises a pin and a spring;   a regulator slot configured to have a regulator disposed therein,
 wherein the regulator comprises a first select position, a second select position, and a third select position, 
 wherein an operator can push the regulator into any one of the select positions using his finger; 
 wherein the pin is configured to secure the regulator into the desired select position, and 
 wherein the regulator is configured to regulate an amount of gas passing through the gas channel. 
   
     
     
         7 . (canceled) 
     
     
         8 . (canceled) 
     
     
         9 . The gas block of  claim 1 , wherein the regulator comprises one or more dents, each dent corresponding to a select position. 
     
     
         10 . The gas block of  claim 9 , wherein the regulator comprises three or more dents. 
     
     
         11 . The gas block of  claim 1 , wherein the regulator comprises three or more select positions, wherein a first select position is configured to allow a first amount of exhaust gas to pass through the gas block, wherein a second select position is configured to allow a second amount of exhaust gas to pass through the gas block, and wherein a third select position is configured to allow a third amount of gas to pass through the gas block. 
     
     
         12 . The gas block of  claim 11 , wherein the first amount of exhaust gas is zero, such that no exhaust gas is allowed to pass through the gas block.
