I know there are several ways to do what I want,,for one I like the look of the brass hex bolt power adapter and can cut the bolt back enough to take it back to stock just because I like the look of it,,play with barrel length and keep it under the limit just because I like a little longer barrel,,don't know why others assume more than what I've said and what my intentions are,,in the end I will not be over 500 fps,,I do know my limits,,there's no way I'm going to be out with an illegal hand gun,,I just have a funky way of getting to where I want to be and it's my money I'm spending to get there,,a thanks to all that gave me information on the subject,,I said in the beginning I would ask a lot of questions,,and I have.
