The ESD Enhanced Foregrip or EFG for short was designed to ease end-users' ability to control their rifle, mitigate recoil, and have faster, more accurate follow-through. From the angle of the ESD EFG to the width, it's made with human-centered design in mind. Its angle allows your wrist to be better aligned with your forearm thus strengthening your overall grip. The width of the Enhanced Foregrip fits perfectly with the length of the proximal flange of a user's hand. RSR - DSG137KJ8RZ0
