So, it's a pistol on a robotic arm, or what? Kinetic weapon doesn't say much.

A pillar with a tiny engine that just incrementally increases the speed could be devastating at a distance though, I'm sure I've read this as some solution to a problem (or attempted solution to some problem) in some sci-fi book, can't remember which though.
