Here's some results of the SS valve made for the Kral guns! Myself have been testing one in an Mrod with great results which I have sent back for some new upgrades that has been come up with since the prototype versions.
This Kral is a Puncher Breaker in .25 with all thats done different is the SS valve and .187 ports.
