Hand Stops not only look great on the rifle but also help you with manipulation. They will prevent you from slipping on the handguard and fixate your hand in one exact position.

Why do you need that? You want to have the same grip every time you operate the rifle to get it in your muscle memory. Primarily when you use pressure pads for flashlights or other switches. You want your hand to be in the same position so that you don’t miss the switch when you need it the most. It will be in the same place every single time because your hand doesn’t shift.
