Looked at it again today. Still double feeding with the mag in. It fires two bb's with one trigger pull. the hop up is in good working conditions and everything else seems to be working fine. the nozzle moves freely still when you push a finger on it.

When i turn the gun upside down and fire it just putting a couple bb's into the hop-up in feeds perfectly. Just when the mags are in it. Can this be mag issues feeding too much bb's into it?

With the hi-cap that came with it. t's still doing the same thing unless I hold the gun upside down :/

Or

could it be that the bucking isn't pushed back enough on the new barrel?
