• Radiused Curved Edges on the new M-Nub to Sync with the Maxx Hop-up’s Window.

• Tough Polycarbonate Construction

Comments: The TDC (Top Down Centre) Trolley is designed for the Maxx Hop-up chambers to incorporate the traditional usage of M-nubs which works perfectly with the ER-Hop (elongated R-hop patches, typically of 6mm in length for long-distance shots). The longer patch would achieve an improvement in accuracy and consistency from shot to shot, typically for sniper DMR builds.
