The SPG-AK was designed to give the shooter ergonomic control of their firearm by matching the natural contour of the shooting hand grip while incorporating a textured front and rear surface allowing the proper use of pressure where it's needed the most. The design of the SPG-AK was inspired by our SFG (Skeleton Forward Grip) and together, they make a great addition to your firearm!
