Little more than an electric shotgun. This is another solution for which there is no problem.
The firing rates of existing equipment are ample for any known needs. What we need is not higher firing rates, but better targeting. Firing and missing is simply a waste of time. A gun that detected a target, aimed with precision, and hit what it aimed at with a SINGLE round would be far better than another stupid scattergun that spews metal all over the place.
