TDC Chamber + Adjuster Set | Marui MWS M4 | Black | TTI

This TDC hop-up unit replaces the complete chamber and adjuster in your Tokyo Marui MWS M4 GBBR. The hop-up controls the backspin on your BB and therefore your trajectory and range. With a top-down TDC system (Top Dead Center), you adjust the hop via a vertical rotary knob on top of the unit, providing a finer and more repeatable adjustment than a standard hop arm. If you are looking for an airsoft hop-up for your MWS platform that keeps the hop consistent during skirmishes, this set is a logical choice when your adjustment drifts or you want more control over your hop.

Technical specifications

The chamber and adjuster are fully CNC-machined from 7075 aluminium and finished in black. The set consists of a one-piece chamber body, a TDC adjuster unit with vertical adjustment knob, a separate hop nub, and a replacement O-ring. The vertical rotary knob features a ribbed surface for grip and a graduated scale with HOP indication for reading your adjustment. The side of the body bears the marking TM-MWS-M4 and the TTI Airsoft logo.

Compatibility and application

This hop-up unit is specifically designed for the Tokyo Marui MWS M4 / AR15 GBBR and fits within that platform. It is an upgrade for users seeking a more advanced hop adjustment in their GBBR build. Installation requires disassembly of the existing chamber and transferring your inner barrel and hop rubber, so some technical experience with the MWS system is recommended.
