I used a pneumatic nutsert gun for my armor and fenders and it works like a champ. It was borrowed but had it not been able to come live at my house I would have forked out the 600 dollars. It takes a little finesse to not over tighten them with the air tool.
One of the other things I did was take some longer hex bolts that were not full length threads and cut the heads off and filed a rounded point onto it. Most of mine where 3 1/2" bolts. I screwed these into the nutserts and could use them to slide the parts up on while tightening the rest of the hardware. There were a couple nutserts where they were pulled in one direction or the other sightly and in that case I would screw the stud in and give a little whack to persuade it in the right direction.
