The Cyma AK Scope Mount fits on airsoft AK-47 style rifles that have a side rail bracket. This will ONLY work with AK guns that have the left-side mount pre-installed. If the left side of your receiver does not have this little rail, this scope mount will not work on your gun. This mount is 100% compatible with SVD sniper rifles too! Finally a mount that works on the A&K SVD (Dragunov) spring rifle!
