The Magpul AFG (Angled Fore-Grip) is a rail-mounted forward grip/index point designed to improve weapon ergonomics and increase shooter speed and efficiency.  Unlike conventional vertical fore-grips, the AFG takes into account natural body mechanics to provide a comfortable and stable user interface, reducing fatique and allowing for more precise weapon control.  By positioning the shooter's hand high on the centerline of the bore, the AFG helps mitigate recoil, facilitating faster, more accurate follow-up shots.
