Hey im just wondering if this will work and/or if there was a better or simpler way to this? Thanks

Ok so i tapped one of my m4 mags to have a male quick connect fitting basically sticking out the side of it so i can connect my remote with a female quick connect. However i have been trying to figure out how to do what this guy did in this video: https://www.youtube.com/watch?v=z3f0DYBORyI&feature=...
