I've aired it up and shot it and it does not leak, so that is good. It's that it is just out of the box from PPS, never on the field, and it seems like it shouldn't be loose already.
You can kind of almost sort of see the gap between the ASA and stab in the pic. It's not ready to fall off or anything. I'd just be more comfortable if it was a tad tighter. I guess I can take the hose off and add an o-ring and re-tighten, not a big deal. Thanks for the help.
I think I'd like to keep the SS hose though. This setup is so tight and it's so pristine I don't want to start toying with things. Macro works great, I have it on my Vikings, but this marker just seems right the way it is.
