You can’t use the stock, as it’s FA. The retaining latch is wider on the FA stock. Modifying the FA latch to fit a SA receiver makes a machinegun.
The bolt groups are well worn on all four kits I’ve had in hand. To the point that I’d use a new bolt to be safe.
The carrier won’t function in a SA stock without removing the anti bounce weights or cutting them shorter. @jbntx did a fantastic write up on this a few years ago here on arfcom.
The best use for the ex-Malay kits by someone who is not a SOT is the Nylaug, which apparently addresses blocking fullauto in some way other than the traditional AUG.
