Removable device for relieving the compression stress on a cocked firing-pin spring of a firearm

Abstract

The device in this patent application will be called an “impact jag”. Similar in size to a bullet, the jag will be a short cylindrical device that can be threaded onto any and all firearms cleaning rods. The unthreaded end of the device will have a flat, blunt surface to be mated firmly against the breech face or bolt face of the firearm to completely cover the firing-pin hole when the cleaning rod is fully inserted into the firearm bore from the muzzle end. To relieve the energy of a stressed firing-pin spring, the firearm is dry fired on the unloaded chamber having the inserted impact jag in place. The released firing pin harmlessly transfers its energy to the impact jag and cleaning rod, or equivalent, thus relieving the stress on the firing-pin spring. After which, the cleaning rod and impact jag are withdrawn from the barrel.

1 . The process of utilizing a cleaning rod, cable, or equivalent to place an impact jag or other similar object against the breech or bolt face of a firearm to cover the firing-pin hole. 
     
     
         2 . The process of performing  claim 1 , above, for the purpose of dry-firing the firearm to decompress the firing-pin spring and minimize any possibility that the spring can weaken or take a set over time. 
     
     
         3 . The process of relieving the compression of a firing-pin spring with a device and then removing the device, leaving the chamber of the firearm empty and safe. 
     
     
         4 . The manufacture of any removable product similar to the described impact jag so that the firearm can be dry fired safely, thus relieving the firing-pin spring without damage to the firing pin and without damage to the firing-pin hole, thus leaving the chamber empty and safe. 
     
     
         5 . The manufacture of any product similar to the described impact jag made of metal, plastic, rubber, or wood, or of any combination thereof whether it be an integral part of a rod or cable, or an attachment to a cleaning rod or cable, so that the firearm can be dry fired, thus relieving the firing-pin spring without damage to the firing pin and without damage to the firing-pin hole, and then removing the product, thus leaving the chamber empty and safe.
