I have a very nice HK made and dated (74 Dated) G3A3 collapsable stock. The stock is in very good condition, locks up tight, some light wear on the metal. The stock is either new un-issued or re-furbed by the Germans, I tend to think the later.
Stock will fit HK91,PTR91,FMP and SAR3/8 stamped steel recievers. It will also fit all in spec stamped G3 type recievers.
$150 plus a bit for the shipping.
I would prefer a USPS MO but I can do the evil on line pay pa;l.
I will do up some pics tomorrow if you need them.
