CNC Hop-Up chamber 4UANTUM MAGNUS PRO PRECISION TDC for Hi-Capa / 1911

MAGNUS PRO 2011 PRECISION TDC Hop-up chamber for Hi-Capa / 1911 gas blowback pistols (Tokyo Marui standard). This precision CNC-machined chamber, made from a solid block of 7075 aluminum, is designed for demanding players who require precise hop-up adjustment and stable inner barrel positioning.

The chamber features a vertical TDC pressure system (Top-Dead-Center), in which the pressure mechanism moves directly up and down. Regardless of the hop-up setting, the pressure point remains in the same position, contributing to a consistent hop-up effect and a more stable BB flight trajectory.

One of its main advantages is the ability to precisely align the inner barrel by adjusting its tilt and lateral alignment (pitch & yaw). Side and frame adjustment screws allow unwanted play between the chamber and the pistol frame to be eliminated. Special barrel retention blocks also hold the inner barrel securely in the correct position without applying uneven pressure, reducing the risk of misalignment or damage.

Thanks to its special adjustment mechanism, the hop-up can be adjusted without removing the slide. Simply lock the slide in the rear position and adjust the hop-up through the ejection port. After disassembling the pistol, the resistance of the adjustment mechanism can also be modified, or the setting can be fully locked to prevent accidental changes.

The recommended hop-up bucking is the 4UANTUM Friction Pro (not included). The chamber is designed for Hi-Capa / 1911 gas blowback pistols based on the Tokyo Marui standard. Minor modifications may be required for proper installation in certain models from other manufacturers. It is not intended for pistols with a different hop-up system design.
