Im not criticizing you im looking for clarification. But I would, you just happened to post this right in front of me.  One problem at a time :)

They're breech-loading rifles, bolt-action rifles, and muzzle-loading firearms. By their nature, they're going to have low cyclic rates when compared to automatic weapons. Azu war fighters offset this weakness by simply shooting things from very long ranges with exceptionally powerful ammunition. With deadly precision to boot.

There's nothing else to really explain. Advanced recoil mitigation systems are a given when discussing futuristic firearms, though it should be noted that azu are not identical to humans when it comes to physical attributes. For one, they're built more robustly, allowing them to endure more recoil than your average homo sapien.
