This rear Picatinny (1913) adapter fits AK pistols such as the Century Arms Draco and NAK-9, Chiappa PAK-9, and any AK pistol with a flat back and receiver width no greater than 1.360". For all flat back receivers, installation requires a .315" hole to be drilled in the rear back plate. Some receivers already have a quick-disconnect (QD) socket on the rear and will not require drilling.
Machined from 6061 aluminum. Unique design has a center locating lug to positively locate the adapter vertically, and side guides to prevent the adapter from rotating. Adapter is threaded and secured by a large 1/4" screw. Made in the USA!
