You can use any of them. The .308 AR differs from their AR15 brethren in the fact that the safety detent and spring are located above (and held in place by) the pistol grip, and not behind the receiver end plate.
If you wish to use a Magpul MIAD grip, you will have to be creative about how that spring/detent are installed. Some people have been known to install a set screw behind the spring. Others have created mounts on the MIAD itself to hold the spring in place.
As far as the MOE and MOE+ go, I am not sure what modifications (if any) are required before mounting.
The Mega Arms MA-Ten does not require a Magpul Grip Wedge
