Hop-Up Chamber Magnus Pro MCX APFG | GBB (gas blowback) | 4uantum

Hop-Up Chamber Magnus Pro MCX APFG | GBB | 4uantum

This hop-up unit controls the backspin on your BB within a GBB replica on the MCX platform, thereby flattening the trajectory. On APFG MCX GBB replicas, the hop-up chamber also plays a role in barrel retention, making this component do more than just adjust the hop-up. You choose this airsoft hop-up when you want a stiffer, single-piece milled hop-up chamber with TDC adjustment within your MCX GBB build.

Technical specifications

This hop-up unit is milled from a single block of 6061 aluminium, resulting in a housing that is executed as one unified piece. The finish is black with several brass-coloured accents on the centring points and the adjustment window. Centring is achieved via a three-point self-centring system with three pins. The hop-up adjustment is performed via a true TDC mechanism that applies pressure along a vertical axis. The adjustment wheel can be operated without a dedicated tool. The geometry has been corrected so that the mechanical interaction during cycling runs via the bolt carrier rather than via the nozzle.

Compatibility and application

This hop-up unit is intended for APFG MCX GBB replicas, including the Rattler, Legacy, SPEAR LT, Rattler LT, RSAR, SURG and MCX HUNTER. BPW MCX GBBs that use the APFG MCX GBB system are also compatible. The unit is not suitable for the APFG XM7 SPEAR GBB, the APFG MPX GBB, MCX GBBs from other brands, or GBB replicas not based on the MCX platform. The adjustment wheel remains accessible via the openings in the handguard, allowing you to make incremental adjustments on the assembled replica between skirmishes, without disassembly. For mounting the unit itself, some build experience with the MCX GBB system is recommended.
