Compatible with most any 1913 Picatinny-railed hand guard, the Magpul AFG (Angled Fore-Grip) takes into account natural body mechanics and provides a comfortable and stable user interface that reduces fatigue and allows for more precise weapon control. By positioning the shooter's hand high on the centerline of the bore, unlike conventional vertical fore-grips, the AFG helps mitigate recoil and control the weapon to facilitate faster, more accurate follow-up shots.
