I talked to Mike at Flying Dragon today . He hoped to have the air tubes delivered to him in a week or so . Looks like it might be a better deal than the Chief . He said the tube has been tested to 6k psi . And the hammer spring is some what light and the valve locks up much above 1800 -2000 psi . I know the quality of my Sentry I bought from him is above the Chief . Marvin
