The Firearm Blog does a review on the Arsenal SM-13 Quick Release Scope Mount for the AK rifle. Check first if you will have to do some modding to make this fit on airsoft AKs if you waant to get this... "In summary, the SM-13 offers a solid, versatile, and easy to install mount that holds zero when in use, and even when removed and reinstalled. Additionally, Arsenal’s SM-13 is well thought out, offering a lot of rail (7.5 inches) while maintaining light weight, and providing a low mounting axis, while still permitting the use of the AK’s iron sights.
