Sure thing, with the leak it runs normally and you can use it just like a new one. Its just when you first connect the air it has a small leak near the elbow/pipe which with a small touch/turn can stop it/seal it up, the advice is that it just needs a new elbow connector thing which is apparently like £4. Saying this you can still use it as it is now used it few weeks ago and may use it in two weeks for a game or two if it hasn't sold. As I said it works and the only reason for selling is I bought a 2011 Reflex
Sorry for not being technical I just play paintball not really into gun parts. If theres anymore questions you would like to ask just go ahead I'd hate to sell to a person who doesn't know exactly what they're getting
