Precision machined from solid 6061 aluminum billet, the Magnus Pro 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.

The innovative tri-lug locking design not only centers the inner barrel, but also locks it firmly in place. A CNC sleeve centers the hop up bucking and holds 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 quick and efficient hop-up adjustments.
