Mods include: full barrel opening ( I don't advise this if you're going to paint it afterwards) 2 cents spring mod ( Because I tried it once and afterwards the spring gets loose so I had to keep it ) air restrictor mod in one of the chamber (because I damaged its spring)
Customizations: sanding of relevant marks and plastic contacts and spray painting the whole thing
Still functional, but not so lean to fire and change darts and it might have lost a bit of power
