The Chinese MAK-90/91 M4 Style Stock Adapter attaches to the MAK-90/91 slant cut Milled Receiver allowing use of the M4 / AR15 style butt stocks and accessories. This adapter incorporates the original rear tang inside the buffer tube. Due to the lack of finish machining in the hole on the rear of these receivers some fitment may be required.

Please remove your butt stock and confirm receiver type before ordering. If you are not able to determine which receiver type you have please send a picture to Send Email and we should be able to help.
