unless ur shootin an invert mini :XThe microline is the hose on the bottom of your gat that goes from the air port to the regulator Cant miss it
I'd love to be able to store air tbh! means I could strip n clean my marker then test to make sure it all work sweet... However I'm forced to co-exist with my brother... who's one of those people who'd use it to threaten his mates if he ever got his hands on it... maybe a lock box me thinks! But cheers for all the helpful ways of draining it!
