It doesn’t have a different outer barrel the outer barrel comes with it as additional part. The z parts barrel alone is £70, and yes it’s basically new as it’s been test fired and that’s it, never been fielded, literally take out the box put a optic on it shot it a little and decided to get a vfc instead.
I don’t see the issue I paid £600 which I know is over priced, but you can’t seem to find them new for under 500, the gun is hardly used, literally test fired it a few times that’s it. Also coming with a z parts 11.5 steel outer barrel which was about £70 not including shipping to get it. Ye it’s 2 tone but it’ll cost little to no money to change the furniture which 99.9% of people do anyways. But if 400 is unreasonable for a gun I paid 600 for and hardly used at all just test fired, I may as well just keep it and do the real steel build I had planned, will just buy a vfc for a secondary built.
