On a colony world, how would you prefer to arm your poorly funded group of explorers, with Reliable, cheap, and easy to produce AK-47s, or extremely complex Coilguns that constantly need repairs from the stress put on them, not to mention a power source, a means to recharge that power source, and the ammunition itself.

Really, AK-47's aren't used much at all nowadays as production of them was stopped in favor of the AKM in the 50's/60's. Its mostly AKMs and AK-74s or variants of those that are used. But, yeah, having weapons that can be run over by a tank and still work would be a valuable tool when resources and technological knowledge are lacking.
