Kral Puncher Pro .357 build.



Puncher Pro will be here tomorrow. It's getting a valve tune, .25" ports from valve to barrel, hammer spring tune, a 28" 357 barrel and full shroud with quiet kit. Should be good for over 100fpe and a decent shot count. The pull bolt design allows for a heavier hammer spring where as the side arm could break.

Now just to deal with the sear and making sure the bolt lug can handle the pressure when fired.
