This is a replacement part for TDC 2.0 version made for genuine Tokyo Marui VSR10 stock hopup chamber.

If you lost the nut or happened to damage the arm, this will get you back up and running. This arm is only compatible with Action Army / Tokyo Marui TDC 2.0 nubs.

This will not work with SSG10 / SSG24 version of TDC 2.0 due to different nub design and thumbscrew length!
