At about 2:15 in the video above, the grip with thumb forward is very similar to how one grips with GoGun gas pedal...
https://youtu.be/6G33QGT0nZUThe Mako/FAB angled foregrip includes a thumb rest with it, but I like to add the gas pedal w/ my magpul AFGs... Color matches very closely too if that's a concern...
Bottom line, gas pedal allows similar grip to original video with much more control -- and also allows me to quickly find repeatable hand positions across different weapons. And it also provides a little space between weapon and hand to help minimize heat transfer to hand when weapon gets hot. I also find it superior to a C-clamp grip for several reasons, and is the closest one can get on to c clamp on weapons like VZ58s or AKs where a c-clamp grip would impede the sights...
Polymer gaspedals can be had for ~$20 on amazon, and the aluminum ones directly from gogun.
