Mine is the AccuTrigger/AccuStock from 2009, so I take it that would mean it's a 4.4 inch? Would this work, then? The 16 is just a SS version of the 10, so I assume so. Only thing that worries me is whether all that's required is replacing the trigger guard, or if other stuff also has to be modified and/or replaced to mount this trigger guard and use the AICS magazines.
