Modular reaction rod with interchangeable head for firearms

Abstract

The present invention provides a reaction rod for working on a firearm comprising a shaft having a distal end and a proximal end, one or more lugs protruding from the proximal end, and a head mounted on the shaft at the proximal end. The head has a tool end, a connection end, and one or more reception points at the connection end, each reception point corresponding with each lug on the shaft and able to accept the lug when the head is mounted to the shaft. The tool end may be configured to engage a set of barrel lugs on a firearm. The distal end of the shaft may be configured for mounting in a vise. An attachment mechanism may secure the head to the shaft. The reaction rod allows for interchangeable heads and facilitates work on firearms without damaging the receiver.

         9 . The modular reaction rod of  claim 8 , wherein the interchangeable head is coupled to the proximal end of the elongated shaft by a connection mechanism having:
 a plurality of lugs protruding from the proximal end of the elongated shaft; and   a plurality of corresponding receptacles on the interchangeable head configured to engage with the plurality of lugs.   
     
     
         10 . The modular reaction rod of  claim 9 , wherein the plurality of lugs and receptacles are arranged in a symmetrical pattern to distribute torque evenly when force is applied to the interchangeable head. 
     
     
         11 . The modular reaction rod of  claim 8 , wherein the mounting portion includes a set of mounting grooves configured to secure the elongated shaft in a vise. 
     
     
         12 . The modular reaction rod of  claim 8 , wherein the shaft is sized to be received into an AR-15 style firearm, an AR-10 style firearm, a similar style firearm, or any combination thereof and the firearm component is a barrel lug. 
     
     
         13 . The modular reaction rod of  claim 8 , wherein the elongated shaft is composed of a lightweight material. 
     
     
         14 . The modular reaction rod of  claim 8 , wherein the interchangeable head is composed of a high-strength material. 
     
     
         15 . The modular reaction rod of  claim 8  wherein the interchangeable head is a first interchangeable head and the first interchangeable head can be exchanged for a second interchangeable head having a second tool end configured to interface with a different firearm type or caliber. 
     
     
         16 . A modular reaction rod for gunsmithing, comprising:
 a rod portion having a distal end and a proximal end;   a vise engagement section at the distal end of the rod portion; and   a first tool head removably attached to the proximal end of the rod portion, the first tool head configured to engage with a firearm component;   wherein the first tool head is interchangeable with a second tool head to adapt the modular reaction rod for use with a second firearm component.   
     
     
         17 .
