This forward biased top rail optic mount is for those AK users who like the optic placed further forward from their eye. This Gen 2 version has a steel insert at the end of its dovetail channel to provide additional strength. The handle is also upgraded to stronger 7075 aluminum. Now you get the best of both worlds: aluminum construction for weight reduction, but steel for strength where it's needed. This mount also accepts AK Masters optional accessory side rail.
