2026 MGW CNC Hop-Up Chamber for Wolverine MTW HPA with GBBR O-ring MAXX MODEL

The MGW CNC Hop-Up Block for the Wolverine MTW by Maxx Model is a fully machined aluminum hop-up chamber, designed exclusively for HPA Wolverine MTW Milspec, MTW Forged, MTW Billet, and MTW-9 replicas. Designed to accommodate GBBR- or VSR-style seals, it features a 360° round nub that replaces the traditional rectangular nub, ensuring uniform pressure on the BB. Its rear HPA inlet module is removable and optimized for the Maxx 2026 ecosystem.

The chamber is secured by a collet-based centering system combined with a CNC-machined aluminum C-clip, a direct evolution from the Delrin C-clip used in the 2024 version. This design ensures stable and precise barrel retention, providing consistent alignment during gameplay. Please note: this block is not compatible with AEG-style O-rings. For airsoft players looking to get the most out of their MTW with a GBBR O-ring, this hop-up block represents a solid and consistent upgrade option.
