4UAD 4UANTUM Magnus Pro AR Hop-Up Chamber for GHK V3 / VFC GBB - Pre-Order Due 24/10/2026

4UAD 4UANTUM Magnus Pro AR Hop-Up Chamber for GHK V3 / VFC GBB 

Machined from solid 6061 aluminium 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.

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 keeps 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.
