Comments: The Chamber True Centrering Unit is especially for the Maxx Hop-up units to address the issue of axial displacement of the chamber caused by two factors.  Firstly the outer barrel and the chamber not fitting snugly onto each other and secondly, loose magazines that could twist the hop-up and inner barrel from aiming at the center.  Once the TCU is fitted, the Maxx chamber will be tightly fitted in place and sitting on the true center position to prevent BBs from swerving to the left or right.
