In volume, a basic system is about $5K per rifle.

On a $1,400 rifle? Ridiculous. Combine the shotgun add-on (similar to the M203) and train skeet-shooting technique.

But that doesn't enrich contractors nor provide kickbacks.

There are 20K ifra-red scopes on 5-10K rifles, not too different. More specialized and complicated electronics on top of a simpler machine. If you don’t think it is going to be more expensive to make a computerized scope than an M4, you are wrong.
