I have run about 100 balls through the longer endgame and have about 40% increase in accuracy. no snake oil was needed. I'm very very happy with it.
don't ask me for test results. its not a new barrel this is a barrel that you have to use to see for your self. it is what it is. Ive let some people shoot it.
so all I can say is hang tight while I get the production ones up and going.
no pricing yet but will say it Will be well worth the wait.
