Hmm, you're correct with regard to the SA-14/QW-2. Just goes to show you that physical appearances can be decieving.
Also, the Misagh-1 is based off the QW-1, and the Misagh 2 is based on the QW-2. You can tell this by the type of battery used, the Misagh-1/QW-1 uses the cylinder, while the Misagh-2/QW-2 uses the one which has the ball like thing on it.
