…Fully-Automatic Rifle. "One of the primary differences in infantry training between NATO countries and the former Warsaw Pact was the use of automatic fire. While NATO countries train their infantry to almost always use semi-automatic fire to engage targets, the Warsaw Pact countries trained their infantry to make use of fully-automatic fire on the assault, in short, controlled three-round bursts. This was a result of the AK-type rifle originally entering service to replace the PPSh-41 as a weapon to deliver fully-automatic fire. As a result of this doctrine, Russian small-arms designers put significant effort into finding ways of making fully-automatic fire with intermediate rifle cartridges more controllable and accurate…"

"short, controlled three-round burst" sounds a lot like semi-automatic fire?? Difference is not clear? |

"short, controlled three-round burst" is exactly how I was trained in the US Army…back in the day. So I guess the US knows the trick, too. |

pzivh43, a three round burst is fully automatic fire, if it was semi-automatic the trigger would have to be pulled three times to fire three rounds. |

My M16A2 has a selection for 3 round burst in the 80's so not new. |

"My M16A2 has a selection for 3 round burst in the 80's so not new." Not relevant for two reasons: 1. When did the AK have a 3 round burst and why did it take so long for the U.S. to introduce it? 2. The article is about something completely different, and vastly more interesting. |

AKs never did have a 3-round burst, their selector is Safe-Full-Semi. burst length is controlled by the shooter. |

An AK is not an "accurate fully automatic"
If you fire it on auto even 3 round bursts it climbs between each shot. Iirc the AKM was fitted with a short flash eliminator which was only on the underside of the barrel to try and counter this tendency. It didn't make much difference, just caused the round to tumble after leaving the barrel. |

Due to recoil after 3 rounds the muzzle is not pointed at the original target. So 3 round burst is the sweet spot between accurate automatic fire versus inaccurate long bursts that waste ammunition. |

I want to play with one of those balanced-recoil systems, seems that they'd be ideal for heavy-recoiling things like shotguns… (can you say "Saiga 12-gauge"?  ) They are annoyingly mechanically complex, though, usually geared to the operating rod that drives the bolt carrier back. As the bolt carrier goes aft, the counterbalance goes forwards, and there are return springs behind both the bolt carrier and counterbalance. |
