4UANTUM MAGNUS PRO 2011 Precision Match TDC Hop-Up Chamber for Hi-Capa/1911 GBBs

The 4UANTUM MAGNUS PRO 2011 Precision Match TDC Hop-Up Chamber is a high-precision upgrade designed for Hi-Capa and 1911 gas blowback pistols. It leverages true vertical Top-Dead-Center (TDC) movement to keep the hop pressure point consistent across all settings, delivering repeatable accuracy for serious shooters.

• Material and Build: Machined from solid 7075 aluminum billet for exceptional rigidity, durability, and long-term consistency under heat and wear.
• True vertical TDC Movement: Maintains the pressure point at a fixed position, ensuring uniform hop-up response regardless of adjustment.
• Patented Design Suite: Comes with over 4 patented designs that enable precise pitch and yaw adjustments for perfect barrel alignment.
• Precision Mounting System: Side and frame take-up screws eliminate tolerances between the hop chamber and frame for rock-solid stability.
• Barrel Fixture Blocks: Specialized blocks secure the inner barrel without applying uneven force, preventing misalignment and internal wear.
• Camshaft Adjustment: Unique camshaft design lets you adjust hop-up without disassembly; lock open the slide and tweak through the ejection port.
• Disassembly Lockdown: A built-in lockdown mechanism lets you tune the resistance of hops or lock the setting completely during maintenance.
• Compatibility: Specifically engineered for 2011-based gas blowback pistols, including Hi-Capa and 1911 platforms, to maximize precision gains.

The Magnus Pro 2011 is engineered to solve common reliability and accuracy issues found in standard hop-up chambers. By stabilizing the pressure point with true vertical movement, it minimizes the drift that can occur as you change BB weight or altitude, helping you shoot tighter groups at various ranges. The combination of rigid mounting, carefully balanced inner barrel support, and a user-friendly adjustment pathway means you can dial in your desired hop with confidence—without waiting for disassembly or fumbling through multi-part assemblies. Field adjustments are straightforward: lock the slide open, tweak via the ejection port using the camshaft system, then lock it down for consistent performance across sessions.
