Sorry no one got back to you. I believe I saw someone attempting this half a year or a year back. I don't remember the details, but it involved installing a makeshift hinge to each side of a cut all the way through the stock.
It didn't look very professional, but I believe the owner had it quite sturdy by the time he was done. You'll probably have to play it by ear for the most part, however.
@Silentfury, There are a few different stock models for clone L96's, but I think the closest it gets is an adjustable/chrome buttplate. I just searched for it, but I'm blanking on the brand so I couldn't find it. Folding stock is something different altogether.
Unless you know something I don't!
if so, a link would be great
