Hey guys its Reverend.
Both me and my teammate have this problem with our sidearms: whenever we put a 12 gram in and pull the trigger to charge the gun, it starts leaking out the back where a remote line adapter can be put (we each have the spot drilled out because of a mod we are trying to do, but thats a different story.
In any sence, would anyone out there possibly know what up? Is it simply and o-ring thing? Have you had the same problem?
