"If you upgrade to this scroll hopup chamber then you do need upgrade the inner barrel too. The OEM old version inner barrel is not compatible with this new chamber. Now I need buy the A&K tight bore to use with this new scroll chamber that I've already bought recentely :O

I think is a good chamber and sealed, but any advice about this possible missunderstanding.
