If your not happy with your CG, though I am not sure why? Then send it to Domi or Zig depending.
Overall the current ones dont really need much work however if your on about the lever protruding this is more related to the Oring in the crown being too big and the pin sleeve is very soft.
The finish is very presentable without mods mate IMHO.
Only the anal PAM guys would do mods And if your reading this then Yes D I am talking about you .....
No matter where you source the CG, if you can, it will always need modding in some way!
