You should try to figure out a way to get an o ring in there. I put an O-ring between the cylinder and air tube of my firelfy and it help out alot. though I think this is a good step.
I'm new to the hobby so my favorites are the newer guns. I like the night finder just couse there is nothing you cant do to the thing, it's so easy to mod. And my absolute favorite is the Firefly, I know it sucks, it does, but I love the feel of it and I love to use the thing.
