Its three-lug self-centering system and TDC adjustment allow for consistent hop-up adjustments, while its corrected geometry directs the chamber's interaction with the bolt carrier rather than the nozzle, minimizing repeated impacts. Stiffer than the stock configuration thanks to its one-piece construction, it also helps secure the barrel on compatible APFG MCX GBB airsoft guns. The adjustment wheel remains accessible through the handguard openings for incremental adjustments without disassembly or tools.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"ficheTechnique\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e \u003cstrong\u003e4UANTUM\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e \u003cstrong\u003eMagnus Pro MCX\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Hop-Up chamber for GBB replica\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061 aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e one-piece housing machined from a solid block\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentering system:\u003c\/strong\u003e three self-centering pins\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHop-Up Adjustment:\u003c\/strong\u003e TDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment:\u003c\/strong\u003e dial accessible through the openings in the handguard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment tool:\u003c\/strong\u003e no dedicated tool required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e APFG MCX GBB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible models:\u003c\/strong\u003e Rattler, Legacy, SPEAR LT, Rattler LT, RSAR, SURG and MCX HUNTER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBPW compatibility:\u003c\/strong\u003e MCX GBB using the APFG MCX GBB system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot compatible with:\u003c\/strong\u003e APFG XM7 SPEAR GBB, APFG MPX GBB, MCX GBB, and other non-MCX GBB brands and models\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eA one-piece chamber machined from 6061 aluminum\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e4UANTUM Magnus Pro MCX\u003c\/strong\u003e is machined from a single block of \u003cstrong\u003e6061 aluminum\u003c\/strong\u003e to form a one-piece receiver. This construction is particularly important on \u003cstrong\u003eAPFG MCX GBB\u003c\/strong\u003e replicas: the Hop-Up chamber also plays a role in the barrel retention interface. Its more rigid and precisely machined design thus contributes to reinforcing the structural rigidity of this assembly.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eThree-pin centering and TDC adjustment\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe chamber incorporates 4UANTUM's \u003cstrong\u003ethree-lug self-centering\u003c\/strong\u003e system and combines it with a true \u003cstrong\u003eTDC\u003c\/strong\u003e adjustment mechanism.
