4uantum MAGNUS PRO Precision TDC Hop Chamber (VFC/GHK AR) GBB

Precision machined from solid 6061 aluminium billet, The MagnusPro Hop-Up chamber features a true vertical TDC (Top-Dead-Center) movement. This means regardless of your hop-up setting, the pressure point remains in the same position for consistent results. Revolutionary self-centring tri-lug locking is the most effective design at not only centring the inner barrel but also holding it firmly in place! CNC bucking sleeve precisely centres the orientation of hop-up bucks and keep it in place for lasting accuracy. The adjustment dial is easily accessed through the ejection port & can be adjusted with any pointed tool without the need for disassembly, allowing efficient & streamlined hop-up tuning.
