Airtech Studios Maxx TDC ER-HOP Trolley & M-nub 6mm Length for Maxx Hop-up Chamber Series

"Completely eliminated the slop in my Maxx ME and VFC 416 body. Now, the chamber is locked in place completely no wiggle. This greatly improved my shot-to-shot accuracy using my Kythera. Any system will benefit from this.

NOTE: Moderate sanding/filing will be needed to achieve a perfect fit. Go slow, and test fit often.
