Tired of those intermittent misfires? 

Firing Pin for 1860 Henry, 1866 Winchester, 1873 Wnichester Rifles

Another product by TK4B Enterprises, LLC. is a newly designed and alloyed firing pin and spring set that replaces those worn, short or broken firing pins. The design incorporates an engineered radiused shoulder that all but eliminates those broken pins we have all had, or seen, in the past. In addition, the alloy used in the manufacture is the same as used to meet the MIL-SPEC requirements for the M-16 and after market AR-15’s.  Plus, TK4B further treats the finished pin with the same heat-treating to nearly the same MIL-SPEC tolerances for smoother, more reliable and longer lasting operation.   

Because there are so many different pressures, tolerances and dimensions between bolts, actions and tune-up styles the firing pin itself is manufactured with extra length in both the shoulder and the pin extension so the installer/tuner can balance the smoother lighter hammer fall to get the proper primer contact for positive firing every time. 

The manufacturers want to clearly point out that if you have little or no idea how these pins are supposed to fit and work, get help or find someone who does know how to install them.  Due to all the variations in machining tolerances on the different rifles this is not a “one-size-fits-all-perfectly” drop-in set. It may/will take some individual fitting. 

The set, which includes a firing pin and a replacement balanced return spring is priced at $20.00 plus shipping. 

The set is designed only for the competent installer to fit and finely tune. 

Made in the United States of America
