T.Lap you could always mag the Rocket. An adjustable kit runs for about $50. But you could make a non-adjustable Mag out of it for only a few $$... Then you just control the amount of mag by adding and removing the number of manets you put in the sideplate.
Just food for thought.
And if you decide to go new, and want to sell-off the Rocket, let me know...
