POTD: Remington/Bushmaster ACR Stock Adapter for AK Rifles
Sureshot Armament Group published these photos of a deactivated AK-12 rifle fitted with a Remington/Bushmaster ACR stock via the adapter they made. Actually, this is not an AK-12-specific adapter and it will work with any AK side folder rear trunnion with a 5.5mm hinge pin.
