Machined from a solid billet of 6061 aluminium, the chamber combines true vertical hop adjustment, self-centring inner-barrel retention and precise bucking alignment to provide a stable and repeatable hop-up setup.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe Magnus Pro is designed around one simple goal: keeping the inner barrel, hop-up bucking and pressure point correctly aligned. Reducing unwanted movement and variation between these components helps create a more consistent backspin and predictable BB trajectory.\u003c\/p\u003e\n\n\u003ch3\u003eTrue vertical TDC adjustment\u003c\/h3\u003e\n\n\u003cp\u003eThe Magnus Pro uses a true TDC (Top Dead Center) adjustment system. As the hop-up is adjusted, the pressure mechanism moves vertically rather than changing the angle of the pressure point.\u003c\/p\u003e\n\n\u003cp\u003eThis means the hop-up pressure remains centred in the same position throughout the adjustment range, helping maintain an even backspin and reducing the possibility of unwanted side spin.\u003c\/p\u003e\n\n\u003ch3\u003eSelf-centring tri-lug barrel locking\u003c\/h3\u003e\n\n\u003cp\u003eThe chamber uses a self-centring three-point locking system to position and secure the inner barrel. Instead of simply holding the barrel in place from one direction, the tri-lug design centres it inside the chamber while locking it firmly against unwanted movement.\u003c\/p\u003e\n\n\u003cp\u003eA precisely machined CNC bucking sleeve also supports the hop-up bucking, helping maintain its correct orientation and preventing it from twisting or shifting during use.\u003c\/p\u003e\n\n\u003ch3\u003eEasy adjustment through the ejection port\u003c\/h3\u003e\n\n\u003cp\u003eThe Magnus Pro adjustment dial can be accessed directly through the replica's ejection port. Hop-up can be adjusted with a suitable pointed tool without removing the hop-up chamber or disassembling the rifle.\u003c\/p\u003e\n\n\u003cp\u003eThis makes fine adjustment significantly easier, especially when tuning the replica for different BB weights or environmental conditions.\u003c\/p\u003e\n\n\u003ch3\u003eGHK and VFC installation\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGHK AR GBB V3:\u003c\/strong\u003e install without the included spacer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVFC AR\/M4 GBB:\u003c\/strong\u003e install with the included spacer\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003ePlease note that GHK compatibility refers to the V3 AR GBB system.
