I have been real busy with a "new" job for the past couple years now so I really have not done more with converting the AR-10 to use the link. Details of what I was looking at are posted in the following thread:

A higher priority for me is to get ahold of one of the Bushmaster 22LR uppers to see if I can modify that bolt to run with the link. A full auto 22LR using the link would be something I would get real excited about as where I live now I am reduced to shooting at indoor ranges...
So, my UZI gets used a lot and the link sits in the safe
