I think, I did wrong typing in some part but some how it still understandable I guess. So If you guys have question about the Mod, feel free to ask at comment section, I will try to answer if I have time.
Some history : This Mod had been made since 2010 https://youtu.be/TRpr4dPI01U
and I actually used almost everyday but I rarely record video and bring it to meeting or even I brought it to meeting, no one want to test or ask about this Mod because bad presented color. After almost 5 years ago of used, grip smelled really bad, So I decided to change whole new grip.(https://www.youtube.com/watch?v=8qJa76hPrs0) After that, every time I brought this Mod to meeting, everyone seem like... I want to try... how to make it. so that why I made Tutorial (even I really lazy to make it lol)
