The Mega 120 is designed around a heavier, ultra-balanced platform. It delivers clean recoil management and smooth lateral tracking; while remaining stiff under serious band load.
26mm inner diameter 
31mm outer diameter 
2.85mm track offset 
Built with optimized ballast distribution and a reinforced hydrodynamic profile, the Mega 120 maintains neutral, controlled buoyancy while offering the confidence needed for long-range shots and heavier shaft configuration. 
This tube will float with a 8mm shaft and does require lead ballasting to achieve neutral buoyancy.
