Rail adapter for mounting over the rear sight of an AK type rifle

摘要

A removable rail for mounting over an AK iron sight assembly of an AK type rifle includes a pair of brackets that fit outer side surfaces of an AK iron sight assembly. At least one pressure clamp is disposed on a side of at least one bracket of the pair of brackets. When the pressure clamp is in an open position, the pair of brackets can be slid over the AK iron sight assembly for mounting or for removal. When the pressure clamp is in a closed position, the pair of brackets are held in a non-moving engagement with the outer side surfaces of the AK iron sight assembly. A fixed AK rail, another type of AK rail, and a method for adding a small arms accessory rail system to an AK rifle by mounting a rail over an AK iron sight assembly are also described.
