Do you have any idea where to get one of those?
I have the Silver version, and i have found that the barrel/hopup is NOT compatible with marui. But it should be able to take the marui one if you switch both chamber and barrel.
My nub ripped on my WE m9...
So I'm trying to get any Barrel assembly I can find. I'd settle for BELL, then I can at least buy a different barrel and bucking.
