The 4UAD 4uantum Magnus Pro AR, is 4UADs attempt to create a leading standard for TDC Hop-Up chambers. Aimed for high performance, consistent results, the Magnus Pro features a tri-patented design solution, featuring a TDC yet user-friendly hop-up chamber that is easily accessible any time for VFC and GHK users, instead of having to disassemble the handguard or have a proprietary tool on hand to adjust the hop.
Centre Locking System
Centering inner barrels with traditional hop up chambers wont always guarantee perfect central alignment with the barrel. With the 4UAD Centre Locking System, it uses a rotatable tensioning ring that pushes 3 knobs at the same time, which not only centres the inner barrel alignment, but a solid, wobble free inner barrel and hop up chamber, improving the consistency and accuracy of each BB shot.
Bucking Shroud
Featuring cuts that indicate how you should mount and align your bucking, it helps with centering your bucking alignment, stabilizing and increase your output velocity.
True TDC Articulation with Quick Hop Up Adjustment Dial
A CNC machined TDC Control Ring Nub, the Magnus Pro TDC control ring has been designed with minimal wobble and a reliable contact between the rubber and chamber. The Magnus Pro comes with 2 control ring options, A Single Contact Control Ring for R-hop or large contact patches buckings, or a Double Contact Control Ring for stock or 4UAD Friction Pro buckings. Foregoing the need of keeping a proprietary hop up adjustment key on hand or having to remove the handguard to access the adjustment dial, the Magnus Pro replaces these options with a precise rotary dial that can be accessed through the ejection port of your VFC / GHK GBB, by simply having a 1.5mm hex key or similar, you just need to pull the dial towards you to increase the hop, or push away to decrease the hop.
