4UANTUM Magnus Pro MCX TDC Hop Up Chamber For APFG MCX GBB Series

MAGNUS PRO MCX PRECISION TDC HOP CHAMBER (APFG MCX)

Machined from a single billet of 6061 aluminum as a one-piece housing, the MAGNUS PRO MCX features our proven self-centering tri-lug design and true TDC adjustment mechanism.
In addition to delivering improved accuracy and consistency, the chamber incorporates corrected cycling geometry. During operation, the chamber interfaces with the bolt carrier rather than the nozzle, helping prevent nozzle damage caused by repeated impact.
Because the APFG MCX uses the Hop chamber as part of the barrel-mounting interface, the MAGNUS PRO MCX also improves overall structural rigidity through its stronger, precisely machined construction.
The adjustment wheel is easily accessible through the handguard openings, allowing smooth incremental adjustments on the go—without disassembly or dedicated tools.

旋力大師 MCX TDC Hop-Up座 (APFG MCX)

旋力大師MCX採用整塊6061鋁合金一體切削加工而成，搭載經過考驗的置中三點式迫緊設計，以及純正的TDC垂直下壓調整機構。
除了大幅提升射擊精度及穩定性之外，此膛座也修正了整體幾何機構。使其運作時，Hop座會與槍機緊密接觸，而非直接撞擊氣嘴，有助於避免氣嘴因反覆撞擊而損壞。
由於APFG MCX將膛座做作為槍管固定介面的一部分，旋力大師MCX透過更堅固的材質和精密加工的一體式設計，進一步提升整體結構剛性。
調整輪可直接透過護木開孔操作，無須拆解槍身或使用專用工具，便於隨時進行精細的無段調整!
