NEW Flat Mount Rear AR stock adapter with a Tactical Skeleton rear stock and upgraded folding adapter for a Hell Pup or other AK pistol Variant. Our new flat mount adapter, positions this rear stock low enough to use the OEM sights. Adapter is thin enough while fitting under the grip, still allowing the use of the OEM grip bolt. *From the front of the adapter to the end of the stock it measures about 8.625" in length.
