Interesting concept, very good read:


Part of the article:

The AO-63 rifle is chambered in 5.45x39mm cartridge. It is gas operated with rotating bolt lockup. The rifle accomplishes the task of having high hit probability and engagement density by having two barrels in side by side orientation. The two barrels almost simultaneously fire a two-shot burst. I say “almost simultaneously” because the gun is designed to shoot the second barrel with a delay of 0.01 seconds. That short delay ensures that the projectiles don’t affect each other’s ballistics which could happen if they left the muzzles exactly at the same time. The rate of fire of this burst fire mode is 6,000 rpm!
