About 30,000 AR15 lengths per second.

Since the muzzle velocity (1km/s) of an AR15 is about 1/15th the speed of Voyager (15km/s), if you had a matryoshka doll of AR15s that could fire other AR15s you would only need 15 nested AR15s to shoot a bullet as fast Voyager is travelling.

Note that this is actually how multi-stage rockets work.

In Russian, Konstantin Tsiolkovsky famously described the "tyranny of the Kalashnikov equation"

Are multi stage bullets a thing?

I don't think so, but there were gryojets, which were half way there. They were bullet-sized rockets fired from a gun with an unrifled barrel that accelerated as they flew, exceeding Mach 1 at terminal velocity.

Supposedly you could literally slap them out of the air if you were at the muzzle, when they had just begun accelerating.

They were in the James Bond movie You Only Live Twice.
