MAXX Model 2026 CNC Hop Up Chamber – M4 & Wolverine MTW

The 2026 MAXX Model hop up chamber is a fresh design for players who want more from their M4 or Wolverine MTW. It's CNC machined from aluminium and comes in four versions, so you can choose the platform you run and the style of bucking you prefer.

Three changes set it apart from older MAXX chambers. A 360° round nub replaces the usual rectangular nub, giving a more even contact patch on the bucking for steadier backspin. The inner barrel is held by an aluminium C-clip and a collet-style centring system, which keeps it straight and secure in the chamber. And the rear HPA inlet is modular, so it can be removed or fitted to suit MAXX's 2026 HPA parts.

Which version do I need?

• M4E – standard M4, AEG-style bucking (MX-HOP050M4E)
• M4G – standard M4, GBB-style bucking (MX-HOP050M4G)
• MEW – Wolverine MTW, AEG-style bucking (MX-HOP050MEW)
• MGW – Wolverine MTW, GBB-style bucking (MX-HOP050MGW)

The MTW versions are made for Wolverine's MTW range, including the Milspec, Forged, Billet and Wolverine MTW-9.
