Nah, the rails on the ASA break sometimes. I think on our team, we've probably broken 3-4 Creed ASAs, and too many barrels to count.
That's part of the game. Practice diving and holding your gun properly when doing that superman...practice with nothing in your hand until you get used to the motion, then graduate back to breaking your equipment, lol.
Now to answer your question.
You can contact overweightangel on here for Creed parts. He may have some. If not, I would check with www.aggressivesports.net
and see if they have the parts. They can also help you out with annodizing.
As far as using an ASA that doesn't require the rails, that won't really work on the Creed because the rail and set screws keep the ASA in place, it's not a direct bolt ASA like some accept. You could get clever if you have a drill press and machine the frame to accept a direct bolt ASA, if you have a tap and die set.
