cock the gun before you air it up. the leak down the barrel comes from the hammer resting against the valve and causing a slight leak. cocking it pulls the hammer back. its normal for cockers.
if you still hear a leak from the body of the gun, then you will probably want to replace the cupseal or valve o-rings. to do so you will want a valve tool, otherwise its very simple to do, it should be easy enough to find a guide.
the bolt will go to the forward position when its aired up. its a closed bolt gun remember.
that means the bolt is in the forward position at rest.
if its leaking from the front of the gun around the pneumatics, its most likely the 3 way. either the o-rings are bad or its out of adjustment. loosen the 3 way shaft from the coupler and pull it out and inspect the o-rings. pay attention to how far it was threaded onto the coupler.
OR....it could just be that the gun has sat for a long time and all the o-rigns are just dry. put a generous
amount of 3 in 1 or your favorite paintball oil (they are the same thing) in the asa and dryfire the **** out of it.
very nice orracle btw.
looks like it has a CCM bolt and aftermarket ram...which could also be a ccm, im not sure what they look like, but thats my guess.
edit: oh, its actually a black to green, wgp's "black" just looks a little purple-ish lol.
