Precision machined from solid 6061 aluminum billet, The MagnusPro Hop-Up chamber features a true vertical TDC (Top-Dead-Center) movement. Which means regardless of your hop-up setting, the pressure point remains in the same position for consistent results.
Revolutionary self-centering tri-lug locking is the most effective design at not only centering the inner barrel but also holding it firmly in place.
CNC bucking sleeve precisely centers the orientation of hop up bucks and keep it in place for lasting accuracy.
The adjustment dial is easily access through the ejection port and can be adjusted with any pointed tool without the need for disassembly, allowing efficient and streamlined hop-up tuning.
The recommended hop-up bucking is 4QUANTUM Friction Pro (not included). The chamber is only compatible with GHK/VFC AR.
