MechLabs ZERO Hop-Up Alignment Cap for NEXXUS / X-MOD HPA Engine
The MechLabs ZERO Cap is a CNC aluminum hop-up alignment base designed specifically for MechLabs NEXXUS and X-MOD mechanical HPA engines. It allows compatible ROTO hop-up chambers to mount directly to the HPA engine, helping maintain proper alignment between the engine nozzle and hop-up chamber. By simplifying the connection between the engine and hop-up unit, the ZERO Cap helps reduce alignment-related installation issues and makes setup and maintenance easier.
